arrow_forward Question PROBLEM The diameter of two pulleys are (0.3m)and (0.2m), center distance (1m).if we use open belt drive. Determine: 1- the length of V-belt (2ß = 60°). 2- the contact angle between belt and smaller pulley. 3- the horse power, if the smaller pulley turn with speed (400r.p.m) and the tension force in tight side (T1=900N), coefficient of friction ų=0.3 4- the speed of large pulley.
Assume that there are no frictional forces between the pulleys and the strings, and the strings are mass-less. The frictional coefficient between the1 kg and 2 kg is 0.05, the frictional coefficient between the 2 kg and 5 kg is 0.1, and the frictional coefficient between the 5 kg and the table is 0.2. (a) Draw free-body diagrams for each mass? (b) Calculate the magnitudes of normal forces and frictional forces?(c) If we release 4 kg and 3 kg from rest what are the accelerations of each mass? (System has two different accelerations)(d) Calculate the tensions in each string?

A worker places an aluminum ladder on a horizontal concrete slab against a vertical wooden wall at 30 degrees from the vertical. The ladder has length L=5m and m=30 kg. The ladder’s CM is at a third of the length up. Worker Bob has mass M=90 kg and intends to climb up the ladder. Simultaneously, worker Charlie has mass M=90 kg and operates a rope through a single pulley to hoist a pail of mass m=30 kg. The axle of the pulley is anchored to the ladder at A=0.3 m along the ladder from the top point. Charlie is pulling the rope down with enough force to hoist the pail at uniform velocity. The mass of the pulley and rope are negligible. The friction in the pulley axle is negligible. The ladder is equipped with rubber booties and a rubber top. The kinetic friction coefficients are: rubber on dry concrete 0.9, rubber on dry wood 0.9, aluminum on wet concrete 0.2, aluminum on wet wood 0.2. b) Repeated use has deteriorated the rubber coating of the ladder, exposing the aluminum under it.

The following must also be included in the answer: 1.) Given and requirement(s), 2.) Free body diagram, 3.) Formulas and their proper symbols, 4.) Direction of forces and sign convention. The vertical and horizontal components must also be indicated in your freebody diagram.
Consider Figure 5.28. The driver attempts to get thecar out of the mud by exerting a perpendicular force of610.0 N, and the distance she pushes in the middle of therope is 1.00 m while she stands 6.00 m away from the caron the left and 6.00 m away from the tree on the right.What is the tension T in the rope, and how do you find theanswer?
