A rigid body, with its center of mass located at the position r G = − 2.76 I ^ + 0.96 J ^ (in), and rotating about the origin A, has a mass of m = 8.24lbm and a moment of inertia about its center of mass of I G = 11.3290 lbf in s2. At the instant shown, it has an angular velocity of θ ˙ = − 0.21 rad/s. In addition to the gravitational force acting in the...

4. (a) Three point masses are attached to a massless rigid rod. Mass m,-1.0 kg is located at x = 1.0 cm, mass m2-2.0 kg at x = 2.0 cm and mass m,-3.0 kg at x-3.0 m. Find the center of mass of the system. (b) Find the center of mass of the four masses as below. mi 2.0 kg at point (1,2) cm; m 3.0 kg at point (2,-3) cm; m -4.0 kg at point (3,-4) cm and m...
(Handwritten if possible please) 2. A pivoted beam has a mass mi suspended from one end and an At- wood's machine suspended from the other (see left-hand sketch) The frictionless pulley has negligible mass and dimension. Gravity is directed downward, and m2 > m3 Find a relation between m,m2.m3, 1i, and h that wil ensure that the beam has no tendency to rotate just after the masses are released M3 m2
Question 22 of 30> The femur of a human leg (mass 10 kg, length 0.9 m) is in traction, as shown in the figure. The center of gravity of the leg is one-third of the distance from the pelvis to the bottom of the foot. Two objects, with masses mi and m2, are hung at the ends of the leg using pulleys to provide upward support. A third object of 8 kg is hung to provide tension along the leg....
A physical or compound pendulum is a rigid body that oscillates due to its own weight about a horizontal axis that does not pass through the center of mass of the body (see Figure). Assume the pendulum of mass M is released from rest from an angle 0. Determine the angular velocity o as function of the angle 0. Note: do not assume that the angles are small

NO 1. A small block with mass 0.500 kg is suspended from the endp' of a rigid massless rod that is 1.60 m long and free to pivot about the far end from the block. The block has an initial velocity of 2.00 m/s to the left at the moment that the rod is perfectly vertical. At that same moment a glob of muck, mmuck 0.040 kg, travelling to the right with constant velocity strikes the block and sticks to...
