Pro 12 The tractor exerts a towing force of T=500 lb. There are two front and two rear tires which provide normal reactions, and the tractive friction F exists only on the two rear tires. Also, discuss whether it will move or not. The tractor has a weight of 7000 lb and a center of graviry at Gr. An additional weight of 600 lb is added to its front for stability, which is indicated by GA. Take us = 0.4. The front wheels are free to roll. TE 2.5 ft. B F 5 ft-1-4 ft--- 3 ft GA

Draw fbd separately ,Better to go with handwritten format.

The uniform 14-ft pole weighs 150 lb. and is supported as shown. Calculate the magnitude of the force P required to move the pole if the coefficient of static friction for each contact location is 0.40. Express your answer in units of lb. 6' A 14' - יך B - P

Please be neat with steps show free body diagram

draw free body diagram and A and B please. picture is pretty clear! Block is labeled A (under A is 25 degrees) above is 45 degrees and F pulling down is 50 degrees

I need a process for this problem

Q3/ If the coefficients of friction between brake am and cylinder C is 0.3 and between cylinder Cand the floor is 0.12, determine the minimum force P required to hold the cylinder from the rotati on. Note that the weight of the cylinder Cis 100 Ib and neglect the weight of the brake arm? 5-15 Higd 20" 10" 0" 1500n-b

The 185-lb man with center of gravity G supports the 83-lb drum as shown. Find the greatest distance x at which the man can position himself without slipping if the coefficient of static friction between his shoes and the ground is 0.43. 15' 83 lb Answer: x = tel ft T 3.3'

The pickup truck pulls the wooden crate, as shown in Figure 2. The truck has a mass of 1.25 Mg and a center of mass at G. The coefficient of static friction between the truck's wheel and the ground is µ = 0.5, and between the wooden crate and the ground is µs' = 0.4. Determine the greatest weight of the wooden crate the pickup truck can pull if:   a) the truck has rear-wheel drive while the front wheels are free to roll, and   b) the truck has four-wheel drive.
