Question

To a light beam (of negligible mass), two antiparallel forces are applied, as shown in the figure. These forces cause a net torque equal to 7.3 Nm (and with the same direction as that caused by F2) at the left end of the beam. If F1 = 7.2 N and F2 = 4.3 N, determine the distance "l" that separates them.

A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.745 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 40.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after she pulls her arms in? distance: about us careers privacy policy terms of use contact us help tv W MacBook Air 8828
A 0.71-m-diameter solid sphere can be rotated about an axis through its center by a torque of 12.8 m∗N which accelerates it uniformly from rest through a total of 170 revolutions in 15.0 s. What is the mass of the sphere? Express your answer to two significant figures and include the appropriate units.
A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.795 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 20.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after she pulls her arms in?
What is the net torque on the beam shown in the figure about an axis through C perpendicular to the page?
Two 1.5 kg spheres of radius 0.20 m are each rotating at 24 rad/s about axes that pass through their centers. One is a thin-walled spherical shell and one is solid. Suddenly, a net torque of 0.12 Nm acts on each sphere and slows the motion down. Which sphere (solid or shell) comes to a halt first?
The distance from the fisherman's hand to the tip of the rod is L = 1.94 m. A fish is on the line, and it pulls the line with a force of F = 110 N at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an axis perpendicular to the page and passing through the fisherman's hand
I am sitting on a seesaw opposite my young nephew. The seesaw is 14.5 feet long and has a pivot in the middle. I weigh 106.4 lbs while my nephew weighs 34.5 lbs. What is the magnitude of the initial net torque on the seesaw (in ft-Ibs)?
If you hold your arm outstretched with your palm upward, the force to keep your arm from falling comes from your deltoid muscle. Assume that the arm with hand has mass 4.25 kg and the distances and angles shown. What is the magnitude of the torque must the deltoid muscle provide to keep the arm in this position, in N·m? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
The figure below shows a fisherman with a fishing pole that makes an angle of 20.0° above the horizontal. The distance from the fisherman's hand to the tip of the pole is L = 1.89 m. A fish is on the line, and it pulls the line with a force of F = 119 N at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an axis perpendicular to the page and passing through the fisherman's hand?
On a playground, there is a merry-go-round. In order to get it moving, Bonnie applies a force of 17 N. The merry-go-round measures 5.3 m from the axis of rotation to the edge where Bonnie applies her force. Assuming she applies her force perpendicularly to a line drawn from the axis of rotation, what is the magnitude of the torque t Bonnie imparts to the merry-go-round? T = N.m

A man ties one end of a strong rope 9.18 m long to the bumper of his truck, 0.561 m from the ground, and the other end to a vertical tree trunk at a height of 3.30 m. He uses the truck to create a tension of 8.17 102 N in the rope. Compute the magnitude of the torque on the tree due to the tension in the rope, with the base of the tree acting as the reference point. N · m
