The rod is in the figure below is confined to move along the
path due to the pins at its ends. At the instant shown, the rod has
an angular velocity radians/second in the counter clockwise
direction. Determine the velocity of points A and B.at this
instant.

8. (10 points) Picture taken from problem 19-21. The spool has a weight of 30 lb and a radius of gyration ko=0.45 ft. A cord is wrapped around the spool's inner hub and the end of the chord is subjected to a horizontal force P = 5 lb. Assume the spool rolls and slips. The coefficient of friction between the spool and the ground is uk = 0.1. Determine the spool's angular velocity in 4 s...
Picture taken from problem 18-42. The spool has a mass of 20 kg and a radius of gyration of ko= 160 mm. If the 15-kg block A is released from rest, determine the distance block A will have fallen at the instant it reaches a velocity of 1.5 meters/second. 200 mm A
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...
< Assignment #7 Problem 13.94 2 of 5 Using a forked rod, a smooth oyinder P, having a mass- of 0.6 kg, is forced to move along the vertical slotted path r (0.60) m, where 0 is in radians. (Figure 1) Part A If the cylinder has a constant speed of vcー1.7 m/s . determine the force ofthe rod and the normal force of the soton the cylinder at the instant rad. Assume the cylinder is in contact with only...
Problem 2.1(10 points) A rod with mass m is starting to move from the initial vertical position on the smooth surface of a table without initial velocity.

This problem is taken from Ahlborn's Zoological Physics, P 5.2. Two young people jump down from a height of h = 2.0 m onto the forest floor which has a mud hole and a rocky flat. The boy (M = 70 kg) lands with stiff legs on the muddy ground, which "gives" so that he depresses the ground by Delta_y = 5 cm when being decelerated from the impact velocity U_0 to 0. Determine the impact speed U_0. Calculate the...
