- A 40-N weight hangs from a (massless inelastic) cord that runs around the outside of a pulley. The pulley is a uniform solid disk of radius 12.8 cm and mass 6.5 kg. You may assume the system is released from rest. Determine the angular acceleration of the pulley. Express your answer in rad/s², to at least one digit after the decimal point. 40 NAsapA wheel of inner radius r, = 14.2 cm and outer radius r, = 35.0 cm shown in the figure below is free to rotate about the axle through the origin o. What is the magnitude of the net torque on the wheel due to the three forces shown? (Assume F, = 3.80 N, F, = 6.20 N, and F, = 14.6 N.) N. m F, 45.0°
- Macmillan Learning The Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. Approximate the pulley as a uniform disk with mass m₂ = 5.13 kg and radius rp=0.450 m. The hanging masses are m = 20.7 kg and mg = 12.7 kg. Calculate the magnitude of the masses' acceleration a and the tension in the left and right ends of the rope, 7₁, and TR. respectively. a= TL = TR = 2 m/s N m₁ 111Two mass (m1 = 6.35 and m2 = 5.31) are attached by a massless string over a pulley on a table (uk = 0.167). The pulley is a disk (mass = 2.35 and radius 0.36). Find the acceleration of the system.Homework
