In a traction drive, a 1.1-in.-diameter cylindrical roller is preloaded against a 3.1-in. diameter cylindrical roller. The steel rollers are 1.6 in. wide and the preload force is 32 lb. The axes of the cylinders are parallel. Calculate the width of contact in inches x 10-5 (e. g. if your answer is 0.0012345, submit 123.45). Also determine the maximum value of the subsurface shear stress.

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
