A uniform plank rests on a level surface as shown below. The plank has a mass of 34 kg and is 6.0 m long. How much mass can be placed at its right end before it tips? (Hint: When the plank is about to tip over, it makes contact with the surface only along its edge at 4.2 m that becomes a momentary axis of rotation.) -4.2 m- 1.8 m Things to consider: 1. At the instant that the plank tips over, where does the normal force from the surface to the plank act? 2. Draw all forces on the plank at the instant of tipping.

A thin spherical shell has a radius of 0.90 m. An applied torque of 920 N m imparts to the shell an angular acceleration equal to 4.70 rad/s2 about an axis through the center of the shell. What is the rotational inertia of the shell about the axis of rotation? Calculate the mass of the shell.
Q6 - A thin, cylindrical rod, l= 24.0 cm long with mass m = 1.20 kg has a ball of diameter d = 8.00 cm and mass M = 2.00 kg attached to one end.

The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center (Figure 1). When his hands and arms are brought in and wrapped around his body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. His hands and arms have a combined mass 8.0 kg. When outstretched, they span 1.6 m ; when wrapped, they form a thin-walled hollow cylinder of radius 26 cm. The moment of inertia about the rotation axis of the remainder of his body is constant and equal to 0.4 kg⋅m2. If his original angular speed is 0.30 rev/s, what is his final angular speed?
The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center ( Ibar=ml² where l is the length of the bar). When the skater's hands and arms are brought in and wrapped around their body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. The hands and arms have a combined mass 10 kg. When outstretched, they span 2.1 m. When wrapped, they form a cylinder of radius 21 cm. The moment of inertia about the rotation axis of the remainder of the body is constant and equal to 0.6 kg-m2. If the original angular speed is 0.5 rev/s, what is the final angular speed? 00f= rev/s Determine how much the figure skater's rotational KE increased. [NOTE: We express energy in J. To get J, you must convert your angular velocities to the appropriate mks. units which are rad/s.] ΔΚΕ- =
A 250-g mass hangs from a string that is wrapped around a pulley, as shown in the figure. The pulley is suspended in such a way that it can rotate freely. When the mass is released, it accelerates toward the floor as the string unwinds. Model the pulley as a uniform solid cylinder of mass 1.00 kg and radius 9.00 cm. Assume that the thread has negligible mass and does not slip or stretch as it unwinds. Determine the magnitude a of the pulley's angular acceleration. rad/s? a = Determine the magnitude of the acceleration a of the descending weight. a = m/s?
