The double pulley consists of two wheels which are attached to one another and turn at the same rate. The pulley has a mass of 15 kg and a radius of gyration kO=110mm. If the block at A has a mass of 40 kg, determine the speed of the block in 3 s after a constant force F=2kN is applied to the rope wrapped around the inner hub of the pulley. The block is originally at rest. Neglect the mass of the rope.
The 3.8 kg block is descending at a rate of 1.2 m/s when the hydraulic cylinder BC exerts a force F=500 N on the brake arm. Determine the number of radians the wheel will rotate before the system comes to rest. The wheel has a mass of 25 kg and a radius of gyration about its center kO=300 mm. The coefficient of kinetic friction between the brake arm and the wheel is 0.25.
The 2.07-kg uniform slender bar has a 0.94-kg particle attached to its end. The spring constant is k = 644 N/m and the distance b = 165 mm. If the bar is released from rest in the horizontal position shown where the spring is unstretched, determine the maximum angular deflection θmax of the bar. Also determine the magnitude of the angular velocity at θ = θmax/2. Neglect friction..
