Suppose there is a 20 m stick that is pivoting about its center of mass at 10 m. On the right side of the stick, you put a 10 N weight 8 m away from the pivot point. Where would you have to put a 20 N weight on the left side of the pivot point (in meters) so that the stick is in equilibrium with zero net torque?
The figure shows five torques applied to a stick. Each stick shown has the same length and is pivoted around the dot. Rank, from least to greatest, the magnitude of torque applied to the stick in each case. If any torques are equal in magnitude, note this in your ranking.
A 2.00-m-long, 500 kg steel uniform beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 70 kg construction worker stands at the far end of the beam. What is the magnitude of the torque about the bolt due to the worker and the weight of the beam?
When a diver gets into a tuck position by pulling in her arms and legs, she increases her angular speed. Before she goes into the tuck position, her angular velocity is 5.5 rad/s and she has a moment of inertia of 1.7 kg · m². Once she gets into the tuck position, her angular speed is 15.1 rad/s. Determine her moment of inertia when she is in the tuck position. Assume the net torque on her is zero. kg · m2
The Achilles tendon inserts on the calcaneus (the heel bone) at a distance of 8 cm from the axis of the ankle joint. If the force generated by the muscles attached to the Achilles tendon is 3000 N, and the moment arm of this force about the ankle joint is 5 cm, what torque is created by these muscles about the ankle joint? Hopefully it’s enough torque to move out of the way so the arrow doesn’t shoot through the tendon.
Two thin rectangular sheets (0.20 m x 0.47 m) are identical. In the first sheet the axis of rotation lies along the 0.20-m side, and in the second it lies along the 0.47-m side. The same torque is applied to each sheet. The first sheet, starting from rest, reaches its final angular velocity in 2.3 s. How long does it take for the second sheet, starting from rest, to reach the same angular velocity? Number i Units
One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts at a 36.1o angle with respect to the length of the stick. Where along the stick is the 6.00-N force applied? Express this distance with respect to the end of the stick that is pinned.
Two uniform solid spheres have the same mass of 2.85 kg, but one has a radius of 0.236 m while the other has a radius of 0.894 m. Each can rotate about an axis through its center. (a) What is the magnitude t of the torque required to bring the smaller sphere from rest to an angular speed of 317 rad/s in 15.5 s? N. m (b) What is the magnitude F of the force that must be applied tangentially at the sphere's equator to provide that torque? N (c) What is the corresponding value of t for the larger sphere? N. m
A playground merry-go-round, made in the shape of a solid disk, has a diameter of 2.50 m and a mass of 350.0 kg. Two children, each of mass 30.0 kg, sit on opposite sides at the edge of the platform. Approximate the children as point masses. What torque is required to bring the merry-go-round from rest to 28.0 rev/min in 23.0 s?
