Get college assignment help at Smashing Essays Question The 25-lb slender rod has a length of 6 ft. Using a collar of negligible mass, its end A is confined to move along the smooth circular bar of radius 32√ ft. End B rests on the floor, for which the coefficient of kinetic friction is μB = 0.56. The bar is released from rest when θ = 30∘.a) Determine the angular acceleration of the bar at this instant, measured clockwise. ATTACHMENT PREVIEW Download attachment Hibbeler14.ch17.p102a.jpg

To use the Principle of Work and Energy to calculate

Question To use the Principle of Work and Energy to calculate the work done by springs, gravity, and friction forces.This Principle of Work and Energy is expressed by the following equation:Ti Unet=Tf.Or, to summarize in words, the initial translational and rotational kinetic energy of a rigid body plus the work done by all the external forces and couple moments acting on the body as it moves from the initial to the final configuration is equal to the final total kinetic energy of the body.a) A spring, k=1060 N/m, is attached to the wall and a mass, m=21.6 kg, using ropes, as shown in the figure.(In the Figure Above)The floor is frictionless and the ropes are massless and inextensible. With the spring in its relaxed state, the distance from the wall to the mass is x0=300 mm.The mass is then pulled to a distance of x1=385 mm from the wall.(In the Figure Above)If the mass is now released, find the first value of x for which the mass will have a speed of 0.517 m/s. b) A man having weight w=150 lb crouches at the end of a diving platform, as shown in the figure.(In the Figure Above)In the crouched position, the diver’s center of gravity is d=1.46 ft above the board and the diver’s radius of gyration about his center of gravity is kG=1.25 ft. While holding this position at θ=0∘, the diver rotates about his toes at A until he loses contact with the platform when θ=90∘. If the diver remains in this crouched position throughout the dive, approximately how many revolutions will he make before striking the water after falling h=16.4 ft?c) A hand-brake system is used to stop a drum, as shown in the figure.(In the Figure Above)The drum has a mass of 95 kg and a radius of gyration about the pin at Oof kO=0.218 m. The coefficient of friction between the brake pad and drum is μk=0.60.If the 14-kg block is moving downward at 2.9 m/s and a force of P=100 N is applied to the brake arm, determine how far the block descends from the instant the brake is applied until it stops. Neglect the thickness of the handle.

To be able to calculate the work done by a

Question To be able to calculate the work done by a couple on a rigid body.When a body subjected to a couple moment, M, undergoes general planar motion, the two couple forces do work only when the body undergoes a rotation. When the body rotates in the plane through a finite angle θ (measured in radians) from θ1 to θ2, the work of a couple isUM=∫θ2θ1MdθIf the couple moment, M, has a constant magnitude, then the work is reduced toUM=M(θ2−θ1)A brake system is tested by rotating a tire and measuring the number of rotations required for the brake system to bring the tire to a stop. (In the Figure Above) The tire’s radius is R = 50.0 cm and the brake system’s radius is r = 18.7 cm . A moment of M = 19.7 N⋅m is applied to the tire for 5 rotations before the brake system is applied. The brake system is composed of two pads that are pushed out against the drum with a force that increases as the tire rotates and is described by F=(10.0θ) N. If the coefficient of kinetic friction between the brake pads and the outer ring of the brake system is μk = 0.550, how many rotations, n, will the tire go through before coming to a stop?
