A mechanic uses a 12 in wrench to turn a bolt. The wrench makes a 30° angle with the horizontal. If the mechanic applies a vertical force of 16 lb on the wrench handle, what is the magnitude of the torque at point P? Express the answer in foot-pounds. (Round your answer to two decimal places.)
The force F = 4 i -7 j moves an object 4 ft along the x-axis in the positive direction. Find the work done if the unit of force is the pound.
Two construction workers are lifting a beam using ropes. Worker A pulls with a force of 500 newtons at an angle of 40°with the positive x-axis. Worker B is on the opposite side pulling with a force of 380 newtons at an angle of 115 ° with the positive x- axis. Find the (a) magnitude and (b) direction angle of the resultant force. (Round to the nearest hundredths)
