(7) Determine the required horizontal force P that the worker must exert on the rope to position the 50 kg crate at rest directly above the center of the trailer. Ans: 126.6 N 1 m 4 m 2 m

Determine the ff: •internal shear force at point c •internal bending moment at point c

A sheet of water of uniform thickness (h = 0.03 m) flows from the device shown in the figure below. The water enters vertically through the inlet pipe and exits horizontally with a speed that varies linearly from 0 to 11 m/s along the 0.2-m length of the slit. Determine the y component of anchoring force necessary to hold this device stationary. FAY = 0 m/s- i 0.2m 0.03m N 11m/s

The compound bar is supported by a thrust bear- ing at A, a slider bearing at B, and the cable CD. Determine the tension in the cable, the force in the bearing at A and the force in the bearing at B. Neglect the weight of the bar.

Determine the force P required to maintain the 195-kg engine in the position for which 0 = 34%. The diameter of the pulley at B is negligible. Answer: P = 2.2 m 2.2 m 195 kg N
