Two children sitting on a See-Saw are not swinging, the net moment on the system is Select one: Equal to weights Zero Equal to Gravity Infinite

A wracking ball is suspended below two cables each at an angle with the horizontal. The left cable has tension T1 and angle 37 degrees with the horizontal. The right cable has tension T2 and angle 22 degrees with the horizontal. The Wracking ball has mass 180 kg. Find the magnitude of tension T2.

Find cable AO or BO or OC force vector.

I would like a more detailed explanation on each step to reach the final answer

The system shown has, F,-231 lbf, F,-172 lbf, M-703 ft-lbs, 0-51, a-1.9ft, b-5.3ft, and e- 3.2ft. f. If the force, F,, is moved to point A, what moment needs to be added to create an equivalent system? a A M e b g. If the moment, M, is moved to point A, what moment needs to be added to create an equivalent system? h. If the force, F2, is moved to point A, what moment needs to be added to create an equivalent system? F

You need to push a cupboard by applying a horizontal force F on its side. The cupboard width is L, height is H and mass is m. You are applying the force at a point that is a height h above the floor. The coefficient of kinetic friction between the dresser and the floor is u. The ground exerts upward normal forces of magnitudes Np and No at the two ends of the dresser. a) How much force do you need to apply for the cupboard to move with constant velocity? b) What are the magnitudes of normal forces Np and Na if the cupboard legs are separated by a distance L? c) What is the maximum height h where you can push the cupboard before it tips over? F H Pl Np N.

See image for question. Thanks.

Draw the FBDs for the following system with its distributed loads simplified to their equivalentloads. Draw the FBD where the system is the bar.  You can find the system in the image provided below.

3. A 550 kg drawbridge has a hinge at one end and a cable attached to the other. It is stuck in a position where it makes an angle of 30° with the vertical. The cable pulling on the far end of the bridge is horizontal. Find the tension in the cable as well as the vertical and horizontal components of force from the hinge.

Show all work: indicate your plan and draw FBD's (Free Body Diagrams), write/label (symbolic) equations (e.g., ZFx = 0) before writing numeric equations, box answers. 1. A 100-lb vertical force is applied to the end of a lever, which is attached to a shaft at O. Determine a) the moment of the 100-lb force about O; b) the horizontal force applied at A that creates the same moment about O; c) the smallest force applied at A that creates the same moment about O; d) how far from the shaft a 240-lb vertical force must act to create the same moment about O; e) whether any one of the forces obtained in parts b, c, or d is equivalent to the original force. 24 in. 60° 100 lb
