How much torque is produced by opening a jar of pickles if the lid on the jar has a radius of 4.3 cm and the force exerted tangentially to the lid is 125 N? Assume that the force is concentrated at one point on the lid.

The wheels of a wagon can be approximated as the combination of a thin outer hoop, of radius ?h=0.156 mrh=0.156 m and mass 5.08 kg5.08 kg, and two thin crossed rods of mass 7.80 kg7.80 kg each. A farmer would like to replace his wheels with uniform disks ?d=0.0525 mtd=0.0525 m thick, made out of a material with a density of 8290 kg8290 kg per cubic meter. If the new wheel is to have the same moment of inertia about its center as the old wheel about its center, what should the radius of the disk be?

When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.80 kg. If the biceps is connected to the forearm a distance of 2.50 cm from the elbow, what is the magnitude of the torque exerted by the biceps to hold a 44.5 N (about 10 lbs) ball at the end of the forearm at distance of 35.0 cm from the elbow, with the forearm parallel to the floor, 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. driceps Biceps dall >

The length of a bicycle pedal arm is 0.137 m, and a downward force of 126 N is applied to the pedal by the rider. What is the magnitude of the torque about the pedal arm's pivot when the arm is at an angle of (a)37.2°, (b) 90°, and (c) 180° with the vertical?

A 70 kg man’s arm, including the hand, can be modeled as a 75-cm-long uniform cylinder with a mass of 3.5 kg. In raising both his arms, from hanging down to straight up, by how much does he raise his center of gravity?

When opening a door, you push on it perpendicularly with a force of 62.6 N at a distance of 0.792m from the hinges. What torque are you exerting relative to the hinges? (Does it matter if you push at the same height as the hinges?)

A horizontal beam of length 2 m and mass 8.0 kg has a mass of 5.0 kg and width 0.8 m sitting at the end of the beam (see the following figure). What is the torque due to gravity (in N. m) on the beam-block system about the support at the wall? (Enter the magnitude.) Wall support 0.8 m, 5.0 kg 2 m, 8.0 kg

Instead of a Tug-of-War competition, two teams are having a "Torque-of-War". Team A is pulling on their rope with a force of 255N at a radius of 0.90m, and Team B is pulling with a force of 180N at a radius of 1.25m. (a) Which team is winning, and what is the net torque on the cylinder? Team A winning (b) The rotational inertia of the cylinder is 34kg*m^(2).

(a) A woman opens a 1.50 m wide door by pushing on it with a force of 44.5 N applied at the center of the door, at an angle perpendicular to the door's surface. What magnitude of torque (in N · m) is applied about an axis through the hinges? N. m (b) A second person opens the same door, using the same force, again directed perpendicular to the surface, but now the force is applied at the edge of the door. What magnitude of torque (in N · m) is applied about the axis through the hinges now? N. m
