6.1 Housing of gearbox

analyse and identify the manufacturing processes used to make the component – both primary (bulk shape forming) and secondary (or finishing) processes. Include sub-sub-section as follows for each component:
o 6.1.1 Component Observations
? Describe your observations of the physical component which indicate what manufacturing processes were performed.
o 6.1.2 Manufacturing Process
? With supporting literature and research, describe the chosen manufacturing process concisely in detail, noting its advantages and disadvantages – describe it in the context of the gearbox you are looking it, not just generally.
? Detail the advantages and disadvantages of these processes
? Relate the chosen method to production volume of the gearbox.
o 6.1.3 Material Relationship
? Relate to the material and its appropriateness in this manufacturing method (e.g. does it have suitable castability?)

Thank you.

Design an longitudinal and cirvumferential connections for boilers that are 2.4 meters in diameter and loaded with pressure of 1 N / mm². The longitudinal joint is made with a triple riveted butt model with an efficiency of about 85% and its cirvumferential connection is a double riveted lap with an efficiency of 70%. The pitch of the outer rivet of the rivet is twice the inner row and the width of the plate cover is not the same. The allowed stresses are:

??_??=77 MPa; ?? = 56 MPa dan ??_??=120 MPa

Assume the rivet resistance to the dual shear force is 1875 times larger than a single shear force.

DRAW / SKETCH the complete connection !.

Thank you.

3. Determine the effective spring constant of the following sandwiches of materials under compressive load (determine the material spring constant only). The material sandwiches are being held in place by a ½-13 UNC bolt, nut, and flat washers on both sides. The first and third materials listed in each sandwich are 0.4” thick and the middle material is 0.04” thick, together making a 0.84” thick sandwich

a. Aluminum, copper-asbestos, steel

b. Steel, copper, steel

c. Steel, rubber, steel

d. Steel, rubber, aluminum

e. Steel, aluminum, steel

A 3/4-6 ACME threaded screw is used to lift a 2 kN load. Note that this has a pitch of 1/6. The mean collar diameter is 4 cm. Find the torque to lift and to lower the load using a ball-bearing thrust washer. What are the efficiencies? Is it self locking? You will need to look up ACME thread size standards online for this problem

In a closed combustion vessel, propane (C3H8) and air are mixed at equivalence ratio of 1.11, temperature of 298 K, and pressure of 1 bar. The mixture is burned to produce solely CO2, CO, H2O, and N2. The heat rejected from the vessel is 820 MJ/kmol of fuel. What are the final temperature and final pressure of the mixture? Since neither O2 nor H2 is present in the burned gas, dissociation can be neglected.

Explain what is Single-Phasing

Particle A (mA = 1 kg) is given initial velocity 10 m/s to the right, while particle B (mB = 1:5 kg) is initially at rest. The coecient of restitution for any impact between A and B is 2/3 while the coecient of restitution for impact of either particle with either wall is 5/6. The particles slide along a smooth horizontal supporting surface. Compute the percentage of the kinetic energy remaining in the system of A and B at the moment just before A impacts the wall on the left for the rst time. (Consider the system to have 100% of its energy at the start.) Neglect all friction.

what are the benefits and disadvantages of a Dynamic Absorber.

Design a gas power plant that works as a non-ideal Regenerative Brayton cycle by determining the pressure ratio required to optimize the net power output of the cycle. The minimum cycle temperature is 300 K while the maximum cycle temperature is 1780 K. The isentropic efficiency of the turbine is 85% while that of the compressor is 75%. The effectiveness of the regenerator is to be taken as 0.8 while the gas flow rate is 30 kg/s. A T-s diagram for the cycle should be provided along with a table showing the pressure and temperature of all the states at the optimized point. Also, mention the cycle efficiency as well as the rate of heat addition and rejection at the optimized point taking the working fluid to be (i) air, and (ii) helium. Ignore pressure drops in the heat exchangers and assume constant specific heats at room temperature

note: i need solution with ees program (detailed information)

List and discuss different robotic applications.

How many constant volume processes are modeled when analyzing an Air Standard Diesel cycle?

Question 10 options:

In a gas turbine plant, air is compressed from 1.01 bar and 15 ?C through a pressure ratio of 4. It is then heated to 650 ?C in a combustion chamber, and expanded back to atmospheric pressure. Calculate the cycle efficiency and work ratio if a perfect heat exchanger is employed. The isentropic efficiencies of the turbine and compressor are 0.85 and 0.80, respectively. ANSWER (0.319, 0.319)
