A wrench is used to apply a torque to a bolt. Forces F1 through F6 all have the same magnitude. The point of application of force F1 (and F4) is a distance d from the center of rotation of the bolt. The application points of F1, F2, and F3 are all distance d apart, as shown. Use the convention that counter-clockwise torques are positive; clockwise torques are negative. Determine the torque applied on the bolt by F6 in terms of the variables and angles given in the problem.

In the image you see a sphere rolling down an inclined plane. Rolling without slipping. Is the weight (mg) producing any torque? Select the correct answer. mg O No O Yes 1P

You are installing a new spark plug in your car, and the manual specifies that it be tightened to a torque that has a magnitude of 14 N·m. Using the data in the figure, determine the magnitude F of the force that you must exert on the wrench.

As a torque activity, your Physics TA sets up the arrangement shown below. 3 F_= A uniform rod of mass m = 118 g and length L = 100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r₁ = 10.0 cm and r₂ = 90.0 cm mark, passed over pulleys, and masses of m₁ = 271 g and m₂ = 137 g are attached. Your TA asks you to determine the following. (a) The position r3 on the rod where you would suspend a mass m3 = 200 g in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert on the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle F, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative). m4 F_= OF = "5 (b) Let's now remove the mass m3 and determine the new mass m4 you would…

Question 4 1 pts A clockwise torque is O negative O positive O torques are always positive Question 5 1 pts Saying that the Sum of torques is zero is the same as saying that the magnitude of clockwise torques is O cqual to the magnitude of counterclockwise torques O opposite to the magnitude of counterclockwise torques O zero Question 6 1 pts For this week's lab, once the pivot is moved away from the center of gravity, the lever arm for the torque of the weight is: O distance between the center of gravity and the position of the pivot O zero O position of the pivot
