A street light hangs from a traffic pole as shown in the figure. The uniform aluminum pole AB is 7.2 m long and has a mass of 12.0 kg. 3.80 m 37 If you take point A as the pivot point, what is the magnitude of the torque exerted by the aluminum pole?

Solve plz

Wolverine has an arm that is 1[m] long and claws that are 0.5[m] long. He's trying to knock over a wall. His shoulder can exert a torque of 1,500[N-m]. What is the ratio of force on the wall with vs without his claws extended? 1.5[m] point Pivot F /F Adamantium Wall without with claws claws A. 2/3 F Wolverine with В. 3/2 with claws С. 1 1.0[m] Pivot Adamantium D. I don't know but the torque direction is point Wall E. I don't know but the torque direction is Fwithout Wolverine Bare hands

A flagpole has a uniform mass density and total mass of M and length L. It is hinged at the ground and makes an angle of U with respect to the horizontal, as shown. To support the pole, a horizontal cable is attached to the pole at a point L from the bottom of the pole. 3 What is the correct sum of torque equation for the axis perpendicular to the page and passing through the bottom of the pole? cable 2L/3 0-Mg + 흙LT=0 O-Mgcos0 +LTsin0 = 0 ○ 들Mgsind + 능TCOS6) +Tcose = 0 Mgsino + LTcos0 = 0 O- Mgsin0+LTcos0 = 0

A gardener is using a tool as shown in the figure to pull weeds. 24 cm You will notice that the tool is designed with a built-in pivot point about which the torques are applied. If the gardener applies a 1.77 Nm torque (about the pivot point) in order to pull a weed, determine the resistive force (in N) the weed exerts on the weed puller. N

The 3.8 m long board shown in the image has a mass of 6.4 kg. The left support is 0.40 m from left end of the board. The right support is 1.2 m from the right end of the board. The cat has a mass of 5.0 kg and starts walking to the right. How far from the right support can the cat walk before the board tips over? (Give your answer in m.) Hints: There are two possible ways to solve this problem 1) Use the center of mass: Find the cat's position when the entire system's center of mass is at the right support. 2) Use torque: Set the pivot point at the right support and find the torque due to the weight of the beam and the weight of the cat. Answer:

A net torque acts clockwise on a 20 kg.m2 object through an angular displacement of 40 rad clockwise. If the initial angular velocity of the object is 20 rad/s clockwise and the final angular velocity of the object is 80 rad/s clockwise, then what is the net torque?

L = 2.0 m A diver with a mass of 43 kg is standing 1.3 m from the left end of a diving board. This diving board has a mass of 83 kg and a length of 2 meters. It is supported by a pillar that is 0.5 m from the left end (labeled F, in the figure) and a bolt that holds the left end down (labeled F2 in the figure). What is the magnitude of the force from the pillar, labeled F1. F = What is the magnitude of the force from the end of the board, labeled F2. F2 = What position could the diver stand at to make both F, and F2 a minimum? 3:45 PM
