Sketch any 1 dof mechanism using 3 or 5 links or any 2 dof mechanism using 4 links provided that all joints are full (revolute/prismatic).

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
