A rod of mass M and length 2L is free to rotate in a vertical plane about an axis through O, as shown in the figure. The axis is normal to the plane of the paper. Three mosses M, M, and 2M are attached to the rod as shown. With the rod in a horizontal position, the system is released from rest. (a) Find the net torque on the rod about the axis of rotation immediately after the system is...

Problem 9 (15 points) A 20-lb slender rod AB is 5 ft long and is pivoted about a point O which is 1 ft from end B. The other end is pressed against a spring of constant k-400 lbin until the spring is compressed 2 in, and the rod is in a horizontal position. If the rod is released from this position, determine its angular velocity and the reaction at the pivot O as the rod passes through a thirty...

A uniform 0.030 kg rod of length 0.40 m rotates in a horizontal plane about a fixed vertical axis through its center. Two small rings, each with a mass of 0.020 kg can slide along the rod. They are initially held by catches at a position 0.050 m on either side of the rod’s center. The rod is rotationally accelerated to 30.0 rpm and then left to spin freely with no friction. While the rod is spinning, the catches are...

4. Blocks of masses 11.0 kg and 25.0 kg hang on opposite sides of a pulley (Atwood's machine) with a massless string that rotates the pulley without slippage. The mass of the pulley is 1.5 kg and it has a radius of 15.0 cm. The heavier mass is 2.5 m above the ground and the lighter mass is 1.2 m above the ground. Using energy consideration, determine the velocity of the two masses when the heavier mass hits the ground....

to the arm of negligible mass which rotates in the vertical plane
about a horizontal axis at O. The 7-lb plug is released
from rest at A and falls into the recess in the block when
the arm has reached the horizontal position. An instant before
