Q4/ Determine the magnitude of the mass (m) in the figure shown. Assume there is no friction in Each pulley, and the weights of all parts are small compared with the load.

The 60 kg two-wheeled cart is described in the figure and parameter table below, with G indicating the location of the center of gravity. It is to be pulled so that it goes up the small step. Find the normal force on each wheel, and the magnitude and direction of the force applied at handle. HINT: remember that there are two wheels sharing the load @080 BY NO SA 2021 Cathy Zupke 4₁1 G L₁ L₂ parameter value 0.6 0.5 0.8 0.7 0.2 A L3 LA d L3 units m m m m m B L₂ F For the answers, take to the right and up to be the positive directions. The normal force at each wheel at A in the x direction is Ax= 150 XN The magnitude of the force at B is F Measured from the positive horizontal axis, the angle of F= 45 X° = 212 XN

The uniform 16-kg plate is welded to the vertical shaft, which is supported by bearings A and B. Calculate the magnitude of the force supported by bearing B during application of the 100-N-m couple to the shaft. The cable from C to D prevents the plate and shaft from turning and the weight of the assembly is carried entirely by bearing A. 220 mm: 100 N-m) B 170 mm 80 mm 600 mm D 480 mm

(5) A B $15⁰ 6 in. 100 lb D C E What is the horizontal force on block E applied by the slider D if a = 4 in.? The slider is on wheels and can translate without friction. Draw free body diagrams of ABC and BD.
