- A force of 60 pounds acts on the pipe wrench shown in the figure below. 18 in. 30⁰ (a) Find the magnitude of the moment about O by evaluating ||OA × F||. (0 ≤ 0 ≤ 180°)Two equal 16.5 kg masses are at the ends of a 4.6 kg 60.5 cm rod that is initially spinning about the rods center at 55.7 rev./sec. suddenly the rods length is increased to 92.3 cm. How fast is the rod (& masses) spinning now? Neglect any frictional interactions in the axle. Enter in your in rev./sec.A physics student with a moment of inertia of 0.600 kg·m2stands on a perfectlymassless, frictionless rotating platform. While at rest, she holds a bicycle wheel with amoment of inertia of 0.280 kg·m2, which is rotating clockwise as seen from above at 7.00rad/s. She turns the wheel upside-down. What is her angular velocity now and in whatdirection (as seen from above)?
- A large turntable rotates about a fixed vertical axis, making one revolution in 5.50s. A child of mass 32.0 kg, initially standing at the center of the turntable, runsout along a radius. When the child is 2.10 m from the center, the turntable makesone revolution in 6.70 s. What is the moment of inertia of the turntable? Note thatyou can treat the child as a point particle.A wheel consists of a thin hoop (mass .20 kg, radius .5m) and 4 spikes (each having a mass of .05kg, length .5m) and is constrained to rotate about its center. There are three forces acting on the wheel: 5N at the outer edge, 3N halfway between the center and the outer edge, and 1N at the center. 1. Find the momentum of inertia of the wheel 2. find the anguar acceleration of the wheel
