A light string can support a stationary hanging load of 22.6 kg before breaking. An object of mass m = 2.79 kg attached to the string rotates on a frictionless, horizontal table in a circle of radius r = 0.815 m, and the other end of the string is held fixed as in the figure below. What range of speeds can the object have before the string breaks? 0 ≤ v ≤ m/s

A thin rod of length L = 2 m, mass m = 3 kg, and moment of inertia I = 4.0 kg⋅m2 is hinged at the top. It is held in place at an angle θ = 40∘ to the horizontal by a horizontal wire, as shown at right. The wire is attached to the rod a distance z = 1.6 m from the hinge. The hinge exerts a force on the top of the rod as well as a constant magnitude frictional torque τ = 5 N⋅m that (along with the wire) tries to keep the rod from rotating. The wire is cut at time t = 0.2) What is the tension in the wire for t < 0? (Yes, you include the frictional torque in your analysis). 3) What is the horizontal component of the force exerted by the hinge on the rod just after the wire is cut? 4) What is the angular speed of the rod when it is vertical for the first time?

A counterweight of mass m = 4.80 kg is attached to a light cord that is wound around a pulley as shown in the figure below. The pulley is a thin hoop of radius R = 6.00 cm and mass M = 1.10 kg. The spokes have negligible mass. (a) What is the net torque on the system about the axle of the pulley? magnitude N⋅m direction (b) When the counterweight has a speed v, the pulley has an angular speed ω = v/R. Determine the magnitude of the total angular momentum of the system about the axle of the pulley. (kg⋅m)v (c) Using your result from (b) and τ→ = dL→/dt, calculate the acceleration of the counterweight. (Enter the magnitude of the acceleration. ) m/s2
