The system is released from rest with no slack in the cable and with the spring stretched 270 mm. Determine the distance straveled by the 18-kg cart before it comes to rest (a) if m approaches zero and (b) if m = 4.3 kg. Assume no mechanical interference. 18 kg 25° k = 243 N/m

The car has a mass of 2000kg. Determine the shortest time it takes for it to reach a speed of 90 km/hr, starting from rest, if the engine drives the front wheels, whereas the rear wheels are free rolling. The coefficient of friction between the wheels and road is s=0.4, k=0.3. Neglect the mass of the wheels. What are the reactions at the front and rear wheels while the car is accelerating

263-sem2-21-22.pdf The 10-kg block A is released from its rest position and slid down the smooth plane. Determine the spring's compression x when the block comes to stop. 10 m A-5 kN/m 30 1 of 1 Q B O 4 U EL

Q1/ The collar A has a mass of 8 kg slides with negligible friction on the fixed vertical shaft. When the collar is released from rest at the bottom position shown, it moves up the shaft under the action of the constant force F = 250 N applied to the cable. Calculate the constant stiffness k which the spring must have if its maximum compression is to be limited to 0.075 m. 225 mm B 450 mm F 75 mm A

The block of weight 8 Ib is released from rest at A and slides down the smooth circular surface AB. It then continues to slide along the horizontal rough surface until it strikes the spring. Determine how far (ft) it compresses the spring before stopping. (uk = 0.2, a= 4 ft,6 = 90 deg, b = 2 ft, k = 40 lb/ ft)

The slotted arm OA rotates about a fixed axis through O. At the instant under consideration, 0 = 37,0 = 44 deg/s, and 0 = 23 deg/s². Determine the magnited of the force F applied by arm OA and the magnitude of the force N applied by the sides of the slot to the 0.5-kg slider B. Neglect all friction, and let L = 0.84 m. The motion occurs in a vertical plane. Answers: F= N= i i -L m N B N 79⁰

During accelerated motion a 5kg ball forms a constant angle ϴ. Determine the angle ϴ and the tension in the rope connecting A to the 15kg block. Neglect the pulley and block A masses, there is no friction between block A and the surface, Leave the result expressed.

The body A with a mass of 50 kg is in equilibrium with the help of the pulling force generated in the AB and AC cables in the middle of the inclined plane and the friction force between the curved surface and the object. The friction force is on the line of motion of body A and develops in the opposite direction to the movement in the direction of the arrow shown in the drawing. Since the pulling force in AB and AC cables is 15.1 and 22.1 N, respectively, calculate the balancer friction force acting on the object vectorially? (g = 9.81 m / s'2)
