The fishing pole in Figure P10.22 makes an angle of 20.0 with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the anglers hand if the fish pulls on the fishing line with a force F=100N at an angle 37.0 below the horizontal? The force is applied at a point 2.00 m from the anglers hands. Figure P10.22
Find the net torque on the wheel in Figure P10.23 about the axle through O, taking a = 10.0 cm and b = 25.0 cm. Figure P10.23
A crane of mass m1 = 3 000 kg supports a load of mass m2 = 10 000 kg as shown in Figure P10.36. The crane is pivoted with a frictionless pin at A and rests against a smooth support at B. Find the reaction forces at (a) point A and (b) point B. Figure P10.36
When tightening a bolt, you push perpendicularly on a wrench with a force of 165 N at a distance of 0.140 m from the center of the bolt. How much torque are you exerting in newton-meters (relative to the center of the bolt)?
In the figure, block 1 has mass m1 = 0.460 kg, block 2 has mass m2 = 0.500 kg, and the pulley, which is mounted on a horizontal axle with negligible friction, has radius R = 0.0500 m. Tension T1, the tension force on block 1, is 4.54N. Tension T2, the tension force on block 2, is 4.87N. What is the net torque acting on the pulley? Please note that I know that the answer is to be that taunet = -T1R + T2R Why is the torque associated with T1 negative when it produces a counterclockwise rotation, and the torque associated with T2 positive when it produces a clockwise rotation? I thought that if the direction of rotation was counterclockwise, then the torque is positive, and if the direction was clockwise, then the torque is negative.

Please note that I know that the answer is to be that taunet = -T1R + T2R Why is tau1 = -T1R? Why is tau2 = T2R? Is the angle between R and the tension force in each case 90o? And so the formula tau = r F sin theta is simply tau = F r = T R here? What about the sign? Here is where I need help: I do not know how to determine the signs of the torques, that is, how to determine the direction of the rotation (clockwise or counterclockwise). Please explain what is the axis of rotation here, and how to determine the direction of the rotation (clockwise or counterclockwise) for this problem specifically and in general. I know that the convention is that if the…
A bolt is tightened by applying a 60 N force to a wrench. If the magnitude of the torque is 120 Nm, and the angle between the force vector and the position vector of the wrench is 30∘, then how long is the wrench? Select one: a. 10 m b. 4 m c. 6 m d. 2 m e. 8 m
The wheels, axle, and handles of a wheelbarrow weigh W = 58 N. The load chamber and its contents weigh WL = 580 N. The drawing shows these two forces in two different wheelbarrow designs. To support the wheelbarrow in equilibrium, the man’s hands apply a force to the handles that is directed vertically upward. Consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper. Find the magnitude of the man’s force for both designs.
To tighten a spark plug, it is recommended that a torque of15 N # m be applied. If a mechanic tightens the spark plug with awrench that is 25 cm long, what is the minimum force necessaryto create the desired torque?
Tweedledum and Tweedledee are carrying a uniform wooden board that is LLL = 3.00 mm long and has a weight of w = 160 N. Tweedledum applies an upward force of magnitude F1 = 60.0 NN at the left end of the board. Which of the following is the correct equation for Στ for the given rotation axis? All rotation axes lie on the x-axis and torques that would cause a counterclockwise rotation are positive. Enter the letter(s) of the correct equation(s) in alphabetical order. For instance, if you thought that choices A, B, and D were correct, you would enter ABD.
