Initially a cable is 20 meters long. The cable is stretched to a length of 20.1 m. The length of the cable is held constant. The material can be modeled using a Maxwell model with an elastic modulus of 2 GPa and a viscosity coefficient of 500 TPa. sec. (30 points) a) Sketch the problem
b) Sketch the Maxwell model
c) Estimate the stress in the cable immediately after stretching
d) Estimate the stress in the cable 24 hours after stretching
e) Estimate the stress in the cable 7 days after stretching
f) Sketch the stress-time curve in the cable

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
