If a 50 lb force is applied to the end of a 70 cm long wrench, how much torque does that produce? Give your answer in ft-lb. Answer to 3 significant digits.

Please answer fast, will appreciate with upvote.

A force is applied to pull a wheel over a step.  Determine the minimum force necessary if h = 3.0 cm, r = 6.0 cm and the wheel has a mass of 1.4 kg.  Use g = 10 N/kg.  Hint: Take torques about the corner of the step.  It is easier to use the perpendicular form of the torque formula because most of the given lever arm information is given perpendicular to the axis of rotation.  To determine the lever arm of the weight of the wheel I set up a 30,60,90 triangle base on h and the radius.

F Pivot d The length of the pool cue is 1.5 m. A force of 11 N is applied at an angle 55°, a distance 0.7 meters from the pivot. What is the torque created? Answer to 3 sig figs.

Suppose you exert a force of 167 N tangential to a 0.255 m radius 75.0 kg grindstone (a solid disk). (Give your answers to at least 2 decimal places.) (a) What torque (in N m) is exerted? (Enter the magnitude.) 42.585 N.m (b) What is the angular acceleration (in rad/s²) assuming negligible opposing friction? (Enter the magnitude.) 2.44 X rad/s² (c) What is the angular acceleration (in rad/s²) if there is an opposing frictional force of 22.6 N exerted 1.75 cm from the axis? (Enter the magnitude.) rad/s²

A man with a weight of 580N is doing push-ups. Please draw a free body diagram to show the forces and place the pivot point where it needs to go and explain why. To calculate the torque, Flsinθ, explain why an angle is not necessary for this problem? What is the force on each foot?

A force of magnitude 30 lbs acts on the end of a wrench as shown.  The wrench is 8 inches long and makes an angle of 30° from the  -x axis in the x-y plane as shown.  What is the torque exerted by this force around point P?  Give the magnitude and direction as a vector.

A torque of 100 Nm rotates the flywheel 200 rad in 10 s starting from rest. The moment of inertia of the wheel is?

What is the net torque about the axle? Express your answer in newton-meters to two significant figures.

Suppose you exert a force of 172 N tangential to a 0.295 m radius 75.0 kg grindstone (a solid disk). (Give your answers to at least 2 decimal places.) (a) What torque (in N · m) is exerted? (Enter the magnitude.) 50.74 N. m (b) What is the angular acceleration (in rad/s?) assuming negligible opposing friction? (Enter the magnitude.) 15.55 rad/s? (c) What is the angular acceleration (in rad/s?) if there is an opposing frictional force of 22.6 N exerted 1.75 cm from the axis? (Enter the magnitude.) 15.44 ]× rad/s²
