A small metal cylinder rests on a circular turntable that is rotating at a constant speed as illustrated in the diagram (Figure 1). The small metal cylinder has a mass of 0.20 kgkg, the coefficient of static friction between the cylinder and the turntable is 0.080, and the cylinder is located 0.15 mm from the center of the turntable. Take the magnitude of the free-fall acceleration to be 9.8 m/s2m/s2. What is the maximum speed vmax�max that the cylinder can move along its circular path without slipping off the turntable?
Two objects are moving in sync with each other in rotation about the same axis of rotation. Object 1 is closer to the axis of rotation than object 2. Object 2 to stay in sync with object 1, therefore, must Move slower than object 1 Move faster than object 1 Move at the same rate as object 1 More information (such as mass, etc) is needed to answer
Problem 1: The figure shows a small sphere of mass m a distance D from the edge of a uniform rod of length L and mass M placed perpendicularly to the rod. The left edge of the rod is placed at the origin of an xy coordinate system. The x-direction points to the right, and the y-direction points up in the figure shown.The rod has a mass of 6.1 kg and the small sphere's mass is half the mass of the rod. The distance D = 1.4 m and the rod has a length of 1.4 m. What is the magnitude of the gravitational force, in newtons, of the ball?
As shown in the figure below, we have a square one meter on a side that is free to rotate about an axis perpendicular to the plane of the square, a distance a from one side and a distance b from the other side. a = b = b (i) Two forces, and F2, are applied to diagonally opposite corners, and act along the sides of the square, first as shown in case (i) and then as shown in case (ii) of the drawing. In each case the net torque produced by the forces is zero. If the magnitude of F2 is 4 times that of F₁, find the distances a and b that locate the axis. It should be noted that a and b are not drawn to scale. m m b a
Mounted on a low-mass rod of length 0.32 m are four balls (see figure below). Two balls (shown in red on the diagram), each of mass 0.83 kg, are mounted at opposite ends of the rod. Two other balls, each of mass 0.31 kg (shown in blue on the diagram), are each mounted a distance 0.08 m from the center of the rod. The rod rotates on an axle through the center of the rod (indicated by the " X " in the diagram), perpendicular to the rod, and it takes 0.9 s to make one full rotation.
Two additional cylinders, identical to the one shown, can each be hung on the bar by hooks from any of the open holes so that the bar will still be in rotational equilibrium when all three cylinders are hanging from it. From which two holes should the two cylinders be hung? Briefly explain your reasoning.
Problem 5: Two blocks are connected with a rope as shown. The surfaces and the pulley are frictionless. The pulley is a disk with radius r and mass m,. A force F is applied to Mass 1 as F m1 shown so that Mass 1 accelerates to the left and Mass 2 accelerates upward. Take the positive direction to the be the direction of accelerations of the masses. (That is, the positive direction for Mass 1 is to the left, and the positive direction for Mass 2 is upward.) mp m2 In the space below, show how you would find the acceleration of the masses. Start with equations from the equation sheet and show your steps to the point where you would calculate the results. You do not need to calculate any numerical result. Just show how you would solve the problem. Be sure your equations reflect the positive direction as described above. Max characters allowed 3000. 0/3000
