True-False

1. The main disadvantage of belts/chains compared to gears is that belts/chains are more likely to transmit noise, shock, and impact than gears are. T/F.

2. A large pulley rotates CCW, meshes with a belt, and the belt meshes with a smaller pulley. The smaller pulley must rotate faster and CCW. T/F.

3. Uniform wear and uniform pressure are simultaneously applied in clutch analysis. T/F.

4. The units on the coefficient of speed fluctuation can be either RPM or rad/sec. T/F.

5. Both clutches and brakes are designed to bring the relative velocity between two mating surfaces to zero. T/F.

Provide an example of steel which has been coated for protection. Explain the coating, fabrication and good and bad points of the coating selection.  

A power train application requires the coupling of a spur gear to a transmission shaft operating at 3600RPM. The coupling must sustain a mean torque loading of 215Nm. There is a 20% torque ripple introduced to the drive line from the load. Select and design a coupling system using either a keyed coupling or an interference coupling such that the section of the transmission shaft at that location is minimized. Assume that the gear is located at the midpoint of the shaft and introduces a steady transverse load of 1000N. The center to center on the bearings is 6.5" (6.5 * 25.4 = 165.1mm)

Given a wall that is 36 feet long and 8 feet high calculate the heat loss per hour when the inside temperature is 70 degrees inside and 10 degrees outside.

The wall assembly consists of:

A = Face brick

B = 1” Polystyrene ins. board

C = 2 X 6 studs

D = Fiberglass batt ins.

E = ½” Sheet rock

F = Paneling

What is a water pump? Why is it important? Give an example with details where a water pump is used: How is it used and how does it help the system?

What safety precautions we need to take in the Powder Metallurgy lab? Please specify and explain

Matlab assignment.

The objectives of this project are (1) to introduce the students to scripting applied to solution of mechanical engineering problems and (2) to create a Matlab script that allows the computation of principal stresses and strains starting from a generic state of stress and that automates the drawing of 3D Mohr circles

Assignment

1) Read from input a stress tensor (3D);

2) For any state of 3D stress compute the principal stress values (σ1, σ2, σ3) with σ1 > σ2 > σ3;

3) Calculate the maximum shear stress (radius of the three circles);

4) Draws the correspondent Mohr circles;

5) Given the principal stresses (computed at point 2) use the Hooke’s law to calculate the correspondent principal strains;

6) Create a flowchart correspondent to this code (Points 1 to 5).

Fluid Mechanics:
The speed of shallow water waves in the ocean (e.g., seismic sea waves or tsunamis) depends only on the still water depth and the acceleration due to gravity. Derive an expression for wave speed.
