In the diagram, a 980 newton crate is attached to a cable. The cable exerts an upward force of 490 newtons on the crate. What is the magnitude and direction of the crate's acceleration?

490 m/s/s upward
490 m/s/s downward
4.9 m/s/s upward
4.9 m/s/s downward

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.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
