Calculate the torque using the moment arm. (Only using a vertical line and ruler.) Hint: Show your work, as usual, start with the equation in symbols, then put in the numbers with units all the way through. If you don't know how to use the equation formatting please handwrite your calculation and upload the image (upright and cropped appropriately).
The answers are provided; please explain the purpose of each equation and why they were used Consider a bar of length 5.5 m, being acted on by three forces and constrained to rotate about its left end. The magnitudes of the first two forces are 19 N and 28 N and the first force is acting on the end of the bar at an angle of 43° What is the torque in newton-meters, due to F1 on this bar relative to the left end? Ans. = 78.87 Nm Equation used: τ1 = rFsinθ What is the torque in newton-meters, due to F2 on this bar relative to the left end, if this force is acting at the midpoint of the bar? Use a coordinate system with positive directed out of the screen. Ans. = 77 Nm Equation used: τ2 = F2 x (L / 2) What is the magnitude of the force F3, in newtons, if the force is a distance 0.85 m from the left end and the bar is not rotating? Ans. = 183.38 N Equation used: F = (τ1 + τ2) / d

Please Use algebra not calculus to answer the following: The picture shows a view from above of a non-uniform object (a rectangular slab with objects placed on it) dropped onto a platform rotating on a low-friction bearing. The mass of the rotating disk is 2.85 kg. 1. Show a Force Diagram 2. Make measurements and calculations to determine the rotational inertia of the slab (including the objects on the slab). Explain your process and results. (Please use the given diagrams to find the rotational inertia) 3. Describe the major assumptions you made during your process. 4. Do you think the actual value of the rotational inertia of the slab (with the objects on it) is more likely to be greater than your value, or less than your value? Support your assertion.
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. *I have to make the equation based off the keyboard provided in the images.

A wrench is used to apply a torque to a bolt. Forces F1 through F6 all have the same magnitude, F, and their directions are per the angle labels in the diagram. For each force, the distance from the point of application to the center of rotation is a multiple of d, as shown. Use the convention that counter-clockwise torques are positive while clockwise torques are negative. Determine the torque generated by F1 in terms of the variables and angles given in the problem statement. Recall the convention for distinguishing clockwise and counterclockwise torques.

Please only type answer For "The Atwood Machine", given the masses of the blocks (m1=2kg and m2=5kg), the mass of the pulley (M=1kg), and the radius of the pulley (R=20 cm) I would like you derive expressions for the acceleration of the system if we include the rotational motion of the pulley. Also derive expressions for the tensions involved. Explain how the acceleration would change if the system were mounted to the top of an elevator that is accelerating up at 5 m/s^2.
