BlockStringRodDiskMech 3.As shown above, a uniform disk is mounted to an axle and is free to rotate without friction. A thinuniform rod is rigidly attached to the disk so that it will rotate with the disk. A block is attached tothe end of the rod. Properties of the disk, rod, and block are as follows.Disk:Зт, radiusR, moment of inertia about center ID = mR²mass =%3DRod:m, length = 2R, moment of inertia about one end IRmR?mass =Block:mass =2mThe system is held in equilibrium with the rod at an angle 0, to the vertical, as shown above, by ahorizontal string of negligible mass with one end attached to the disk and the other to a wall. Expressyour answers to the following in terms of m, R, 00, and g.(a) Determine the tension in the string.

Problem 2: A car is pushing a barrel to the right. The pushing force P is applied by the front bumper which is level with the center G of the barrel (see figure). The barrel has mass m, radius R, and radius of gyration kG. The coefficients of static and kinetic friction between the bumper and the barrel are µs and µk. The coefficients of static and kinetic friction between the barrel and the road are also µs and µk. 1) If the barrel doesn't slip on the road, find the acceleration of the barrel and the minimum value of us required to ensure no slipping. 2) If the barrel slips on the road, find the acceleration of G and the angular acceleration of the barrel.

Suppose a 30 lb truck wheel 18 in. in diameter has a radius of gyration of 4 in. and the 6120 lb truck’s weight is distributed equally to each of the four wheels.a. If the truck can supply 150 lb x ft of torque to each wheel, how fast would the wheel want to accelerate if it didn’t slip? b. What would the coefficient of friction have to be in order to keep the wheel from slipping
A gear engine automobile is traveling along a curved track of 120m radius. Each of the four wheels has a moment of inertia of 2.3 kg m2 and an effective diameter of 600 mm. The rotating parts of the engine have a moment of inertia of1.25kg m2 the gear ratio of the engine to back wheel is 3:2.The engine axis is parallel to the gear axle and the crank shaft rotates in the same sense as the road wheels. The mass of the vehicle is 2050 kg and the center of mass is 520 mm above the road level. The width by the track is 1.6m, what will be the limiting speed of the vehicle if all the four wheels maintain contact with the road surface (b) Explain the function of a flywheel from a crank effort diagram.
The structure of a football goal is shown in the figure below. The bending motion of the structure can be represented by a flexible cantilever beam with tip mass M¡ as shown in the figure. The tip mass M, represents the mass of the horizontal crossbar which is assumed to be rigid in this motion. A single vertical straight beam having mass of MH, shown in the figure below, is the equivalent model for the two symmetrical vertical posts. A soccer ball of mass M, hits the horizontal crossbar with the velocity of Vp. x(t) м, VINGLI SOLAR The response of the horizontal crossbar, mass M, is shown by x(t) in the figure. The vertical beam has a circular cross section of radius r, Young's modulus E and length L. For numerical calculations, use M, = 23.2130 kg, MH = 28.6617 kg. M, = 0.5497 kg, Vý = 8.8974 m/s, L= 2.7757 m, E = 133.5685 GPa andr= 0.0437 m.

The thin rod in the figure has a mass of 15kg and is attached to a spring of constant k = 50 N / m at one end, which has an unstretched length of 1.5 m. If the rod is released from rest in horizontal position (e = 0 °) and only conservative forces act on it, determine: a) What is the moment of inertia of the thin rod around the axis of rotation at A? b) What is the angle at which the rod is momentarily at rest again? c) What is the maximum angular velocity of the path? 2 m 2 m ww. 60

7. 2) The lawn roller has a mass m = 55 kg and a radius of gyration about its gravitational center G, kG = 196 mm. It has a handle that connects to its center axle, and the handle is pushed forward with a force F = 420 N at a 45° angle. The coefficients of static and kinetic friction between the roller and the ground are us = 0.11 and Hk = 0.08, respectively. For the sets of parameters listed below, determine the magnitude of the roller's angular acceleration (in rad/s²). Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s?. F 45° 200 mm A
A sphere of mass M and radius R is not necessarily solid or hollow. It has moment of inertia I= cMR2. As shown in the figure, the sphere starts from rest and rolls without slipping down a ramp from height H. It then moves back up the other side, but now with no friction at all between the sphere and the ramp. What height does the sphere reach?
A wheel is attached by a cable to a block The wheel has a radius of 2ft and weighs 300lbs, the block weights 20lbs. If the radius of gyration about the point of rotation of the disk is 1.5ft, how many revolutions will it take for the wheel to come to a stop assuming it was moving at 10 rad/s CW. Assume the block is on the left side of the wheel and thus causes a CCW moment.
