• Who are your potential customers?

• What makes your business unique in the marketplace?

3. What are the strengths? After you choose a business form, explain the following:

What are the strengths or benefits of this type of business form concerning taxes and liability based on the type of ownership and customer?

4. What are the weaknesses? Do you need a Board of Directors? What are the pitfalls of this type of structure and why based on the type of business being conducted?

Why is it true that k>1 always, where k is the specific heat ratio?

Design a roller chain drive with the following data. Specify the chain size, the sizes and number of teeth in the sprockets, the number of chain pitches, the center distance, and the angle of wrap of the chain for each sprocket. Specify the Tables and Diagrams you use in the solution. Driver type: Hydraulic drive Driven machine: Rock crusher Input speed (rpm): 655 Input power (hp): 120 Nominal output speed (rpm): 200 Number of strands: 4

why is pressure constant for the combustion process of a diesel cycle?

Compare and contrast the Thring sufficiency concept (section 6.5 and figure 6.6 ) with
the Bellagio principles for sustainable development (section 6.6). List specific applica-
tions of each approach to a particular energy issue of interest to you (e.g., urban trans-
portation, expanding energy services in a remote region, recreation). For example, would
playing outdoor sports like baseball, football, and soccer at night or in domed stadiums
be good sustainable practices?

Instructions: Florida Power and Light (FPL) are seeking to add two more nuclear power plants on the current Homestead location where two nuclear power plants already exist.

FPL seeks two more South Florida nuclear reactors article http://articles.sun-sentinel.com/2014-05-12/business/fl-fpl-nuclear-preview-20140512_1_turkey-point-fpl-reactors
Based on what you have learned so far from this class, discuss the following:

What problems might these new power plants encounter if they were built in South Florida with a lifespan of 40 years?
What advantages are there in giving FPL the licenses for these new plants?
What disadvantages are there in giving FPL the licenses for these new plants?
What are some other alternatives to the nuclear power plants?
What precautions would you demand if these power plants were built?
Given what you know, if you were in a position to approve or disapprove the licenses, what would you vote, and why?
Make sure to:

Write a short essay or paragraph of at least 300 words.

1) A car is moving without slipping, it will have a point on its body that has zero velocity. True or False?

2) When a wheel fixed at the center, rotates and accelerate in the same direction, which of the following is generated at a point on the edge of the wheel. - Radial acceleration - Tangential acceleration - Neither radial nor tangential acceleration - Both radial and tangential acceleration

3) If a circular disk is fixed at a point located on its edge and has an angular acceleration, its mass center will only have a rotational inertia and no linear acceleration. True or False?

4) Two cylinders, A and B, of the same size and mass roll down an inclined plane without slipping. Cylinder A has most of its mass concentrated at the rim, while cylinder B has most of its mass concentrated near the center. Which Cylinder will accelerate faster?

5) A wheel of radius 1m is spinning around its center with a constant angular velocity of 2rad/s. What is the tangential component of acceleration of a point located at the rim of the wheel?

6) If a rigid body is undergoing a curvilinear translation, the linear velocity of all the points on the body will be the same. True or False?

7) Consider a cart on a horizontal frictionless surface. Once the car has been given a push and released, what will happen to the cart? - Continue with constant acceleration - Slowly come to a stop - continue with decreasing acceleration - Continue with constant velocity - Immediately come to a stop

8) Consider two identical blocks of the same mass, one resting on a flat surface, and the other resting on an incline. For which case is the normal force greater?

9) The potential energy of a rigid body depends on - Weight of the body - Height at which it's placed - Both

10) A small car collides with a large truck. Which will experience the greater impact force? - Car - Truck - Both the same - Depends on the velocity of each - Depends on the mass of each

11) Two tug of war opponent each pull with a force of 160 N on opposite ends of the rope. What is the tension on the rope?

12) A wheel is rolling without slipping and traveling to the right. In which direction the friction force will act on the wheel? - To the right - To the left

13) When an elastic spring is deflected, its potential energy will depend on the original unstretched length of the spring. True or False?

14) A plate is placed in the x-y plane and a force is applied so that it rotates about the x-axis. Which mass moment of inertia is applicable: - About the x-axis - About the y-axis - About the x-axis

15) If a rigid body is in General Plane Motion ( with translation and rotation) it's kinetic energy is influenced by its mass moment of inertia. True or False?

A power press makes steel pressings. The energy required for each pressing is 5000J with each pressing taking 1s. The time taken to remove the pressing and get the material ready for the next pressing is 4s.If the press is operated by an electric motor which runs continuously with a flywheel used to supply the extra torque required for the pressing. Determine the power of the motor that is required, the energy that has to be supplied by the flywheel and the moment of inertia of the flywheel if it’s speed is not to drop by more than 30 RPM from a speed of 600 RPM.

What is required for 2 processes (like heat and mass) to be considered analogous?

1) What is the difference of dynamic compressor (blowers) and normal compressor? Name 2 types of pump from each category

2 )Sketch and explain two types of blowers;

If a gas is flowing at 300m/s and has a pressure and temperature of 90kPa and
20°C, find the maximum possible velocity that could be generated by expansion
of this gas if the gas is air and if it is helium

Material A is generating heat at a rate of 11.25 x 10^3 W/m^3 and is 40cm thick and has a thermal conductivity of 10 W/mK. Material B is 50 cm thick with an unknown thermal conductiviy. material C is 30 cm thick and has an unknown thermal conductivity. The structure is cooled by a fluid on both sides at 25 (C) with a heat transfer coefficient of 100 W/m^2K. If your thermocouples measure T1 to be 145 (C) and T2 to be 195 (C), find the thermal conductivites of materials B and C.
