- The 40-lb spool is suspended from the hanger GA and rests against a vertical wall. The center of gravity of the spool is at G and the weight of the hanger is negligible. The wire wound around the hub of the spool is extracted by pulling its end with the force P. If the coefficient of static friction between the spool and the wall is 0.25, determine the smallest P that will extract the wire.The brake pads at C and D are pressed against the cylinder by the spring BF. The coefficient of static friction between each pad and the cylinder is 0.15. Find the smallest tension in the spring that would prevent the cylinder from rotating when the clockwise couple M=2200lbin. is applied. Neglect the weights of the members.The block of weight W is pulled by the force P inclined at the angle to the horizontal. Find the smallest force P and the corresponding angle that would cause impending sliding of the block. The angle of static friction between the block and the ground is s.

- 950 mm G₂ azo 425 mm 380 mm 440 mm 500 mm The four-wheel drive all-terrain vehicle (ATV) has a mass of 300 kg with center of mass G2. The driver has a mass of 92 kg with center of mass G1. If all four wheels are observed to skid momentarily when the driver tries to move forward, what is the normal reaction on each of the rear tires? The coefficient of friction between the tires and the ground is 0.43The mechanism shown consists of a crank (bar AB), a connecting rod (bar BC) and the piston C that slides on the smooth surface (without friction). The combustion of gasoline produces a force P on the piston and this is kept in equilibrium with the moment M applied in A. The length of the crank is 116 mm, the length of the connecting rod is 183 mm, the force P is 710 N and the angle theta is 0.56 radians. Determine the value of M in Nm.For the system shown, solve for the maximum mass M that can be suspended as shown and still maintain equilibrium. The masses of A and B are 55 kg and 135 kg, respectively. The coefficient of static friction between block B and the surface C 20° A is 0.12 and the coefficient of static friction between blocks A and B is 0.10. The M coefficient of friction between the rope and the pulley is 0.10.
