PLEASE PUT SOLUTION (WHY) // WHY THE REASON OF THAT ANSWER (?) 1. What should be done to increase the generated torque on a bar, with one end fixed to a point, without increasing the applied force? A. Make the moment arm shorter. B. Increase the weight of the moment arm. C. Move the axis of rotation closer to the point where force is applied. D. Increase the length of the moment arm. 2. How will the generated torque change if you move the axis of rotation from the middle of a bar to its left end, given that the applied force is applied at its right end? A. Torque will be doubled. B. Torque will increase 1.5 times the original. C. Torque will remain the same. D. Torque will be halved.
How many forces provide the counterclockwise torque in the first part of the experiment? P.s. I had this question answered but I was confused on what the actually answer is. Is there only one force or three forces providing the couterclockwise torque? Please clarify more.
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 help me with this and show me your solution. Thank you! From the simulation in the picture, what is the force (N), level arm (m), and Torque (N-m) of the 3 bricks? Complete the table.
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 force of 50 N is applied at the end of a wrench handle that is 24 cm long. The force is applied in a direction perpendicular to the handle.a. What is the torque applied to the nut by the wrench?b. What would the torque be if the force were applied halfway up the handle instead of at the end? Use the CORRECT formula to solve and get the correct answer.

What does the scale (at the center of the rod) read? What is the force the supporting rod applied to the massless rod? Please label each force on the diagram and indicate the pivot point you chose when calculate the torque.
Below is a sketch of the toy on a rotor ride at the moment after the floor drops. The rotor has a radius of R and the toy has mass m. Assume the angular velocity is constant, and the toy is not slipping downward. write Newton’s Second Law for the x and y directions. Use algebra and your equations above to predict the minimum angular velocity ωmin necessary to keep the toy “stuck” to the side of the rotation tube. Express your answer in terms of g, μs, R. (nonumbers yet). Show all of your work and your final result below.
For this problem, refer to the figure on the right. Which force will cause the smallest torque? The axis of rotation is located on the left end as shown in the diagram. Assume all forces have equal magnitude.
Consider a bar, of length 5.5 m, shown in the figure, being acted on by three forces. The magnitudes of the first two forces are 23 N and 28 N, and the first force is acting on the end of the bar at an angle of 54° as shown. a)What is the torque, in newton-meters, due to F1 on this bar relative to the left end? Use a coordinate system with positive directed out of the screen. b)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. c)What is the magnitude of the force F3, in newtons, if the force is a distance 0.65 m from the left end and the bar is not rotating?
From Part A to C, torque is the analog of force and moment of inertia is the analog of mass. Force and mass are physical quantities which are depend on ONLY one factor. For instance, mass is related to the numbers of atoms in an object. Does torque and moment of inertia have similarly in common? Briefly discuss in term of factors that contribute to the torque and moment of inertia.
