Based on Problem 5-87 from the textbook. Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is tramsitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components of reaciotn at the journal bearing C and thrust bearing D. The bearings are in proper alignment and exrt only force reactions on the shaft. FI=70N F2=80 N 300 mm F3 = 40 N 8=44² 250 mm 200 mm F2 80 mm A Z -150 mm B T F

The pinion (gear 2 on shaft a) rotates at 635 rev/min clockwise and transmits 1305 W through the idler pair (gears 3 and 4 on shaft b) to the output gear (gear 5 on shaft c). Gears 2 and 3 have a module of 2 mm, and gears 4 and 5 have a module of 3 mm. Pressure angles are all 20 degrees. Solve for the magnitude of the force that shaft b must apply to gears 3 and 4 to maintain static equilibrium in the figure shown here. The figure is not to scale.

Correct answer I see

The operation of the exhaust and intake valves in an automobile engine consists of cam C, pushrod DE, rocker arm EFG which is hinged at F and on a spring , and valve V. If the compression on the spring is 20 mm when the valve is open, as indicated in the figure, determine the normal force acting on the lobe of the cam at C. Assume that the cam and the bearings at H, I, and J are smooth. The spring has a stiffness of 300N/m. draw the free body diagram
