2D Equilibrium Problems

A 3.0 m wood plank is supported by two scales. One scale is at the right end of the plank. The other scale is positioned such that it reads 620 N. If the mass of the plank is 85 kg, how far is the second scale from the right end of the plank?

A 15,000-N crane pivots around a friction-free axle at its base and is supported by a cable making a 25° angle with the crane (Fig. E11.18). The crane is 16 m long and is not uniform, its center of gravity being 7.0 m from the axle as measured along the crane. The cable is attached 3.0 m from the upper end of the crane. <img src="https://lightcat-files.s3.amazonaws.com/problem_images/bf99904a84578a4e-crane%20improve.png" alt="" /> When the crane is raised to 55° above the horizontal hold-ing an 11,000-N pallet of bricks by a 2.2-m, very light cord, find (a) the tension in the cable. Start with a free-body diagram of the crane.

How to Solve a 2D Equilibrium Problem - Step by Step Solution

Suppose a certain car has a track width of 1.6 m and a center of gravity located 0.40 m above the center of the track. What is the critical angle for this car?

Inclined beam against the floor

A 200 kg, 10 m-long beam is held at equilibrium by a hinge on the floor and a force you apply on it via a light rope connected to its edge, as shown. The beam is held at 53° above the horizontal, and your rope makes an angle of 30° with it. Calculate the angle that the Net Force of the hinge makes with the horizontal (use +/– for above/below +x, and use g=10 m/s2.)<img src="https://static.studychannel.pearsonprd.tech/courses/physics/thumbnails/images/f3ba5648"alt=""/>
