The slotted arm OA rotates about a horizontal axis through point O. The 0.21-kg slider P moves with negligible friction in the slot and is controlled by the inextensible cable BP. For the instant under consideration, 0 = 24,0 = 0 = 5.3 rad/s, 0 = 0, and r = 0.51 m. Determine the corresponding values of the tension T in cable BP and the force reaction R perpendicular to the slot. The force R is positive if the contact comes from the lower edge of the slot and negative if the contact comes from the top edge.

The "flying car" is a ride at an amusement park which consists of a car having wheels that roll along a track mounted inside a rotating drum. By design the car cannot fall off the track, however motion of the car is developed by applying the car's brake, thereby gripping the car to the track and allowing it to move with a constant speed of the track, vt = 3 m/s. The rider applies the brake when going from B to A and then releases it at the top of the drum, A, so that the car coasts freely down along the track to B (0 = π rad). Neglect friction during the motion from A to B. The rider and car have a total mass of 390 kg and the center of mass of the car and rider moves along a circular path having a radius of R = 9.8 m.

3. Two blocks are connected by a massless string horizontally. The left block is pulled by a 100N force 30° above horizontal as shown in the figure. Assume the coefficient of kinetic friction between the blocks and the supporting surface is 0.15. (a) Show all the forces acting on each block by drawing its free body diagram. Determine (b) the tension T of the string connecting the blocks and (c) the acceleration a of the blocks. F = 100N 30° 100N T 200N Pk=0.15

Figure Q1(b) shows the 10 kg rod AB which is constrained so that its end of slider block B move along the fixed guide. The rod is initially at rest when angle = 0O. If the slider block A is acted upon by a vertical force P = (98) N     URGENT!!!!! HELP!!!!!

The system shown below is released from rest. The static and kinetic coefficients of friction between slider A and the rail are 0.8 and 0.2, respectively. Consider massless-frictionless pulleys and massless cable. Mass of slider B is 15 kg and force P= 25 Newtons is always acting on it. If the acceleration of slider B during the motion is 5 m to the right, determine the tension developed in the cable in Newtons. Consider g =10 m.

The slotted arm OA rotates about a horizontal axis through point O. The 0.18-kg slider P moves with negligible friction in the slot and is controlled by the inextensible cable BP. For the instant under consideration, θ=26∘, ω=θ˙=4.6 rad/s, θ¨=0, and r=0.63 m. Determine the corresponding values of the tension T in cable BP and the force reaction R perpendicular to the slot. The force R is positive if the contact comes from the lower edge of the slot and negative if the contact comes from the top edge. I found R to be equal to 1.05 which is correct, I can't find T.

3. A 5-kg crate is released from rest at Point A of a 20-kg ramp which is inclined at 40 degrees as shown in the figure below. The lengths of the ramp is 2 m. The interface between the ramp and the ground can be assumed to be frictionless. Use Newton's 2nd Law and the definition of the center of mass to determine the horizontal distance that the ramp has moved when the crate reaches Point B. Neglect the size of the crate. Does your answer depend on the frictional force between the crate and the ramp? e S
