Hi I needed help with this question. As shown in the figure below, a uniform beam is supported by a cable at one end and the force of friction at the other end. The cable makes an angle of ? = 30°, the length of the beam is L = 2.00 m, the coefficient of static friction between the wall and the beam is ?s = 0.600 and the weight of the beam is represented by w. Determine the minimum distance x from point A at which an additional weight 2w (twice the weight of the rod) can be hung without causing the rod to slip at point A. X=?
A worker is using a 4.0 m long steel bar as a lever to raise one side of a car off the road. The fulcrum is a large block of wood. The magnitude of the load force is $200 N. If the load arm is 0.40 m, calculate the magnitude of the effort force required to balance the load.
An athlete strengthens her leg and knee by doing "leg curls." While sitting on a bench with the leg initially bent at the knee, she supports a weight with the foot. She then slowly raises the foot and lower leg, with the upper leg held stationary. Find the tension in the quadriceps tendon for the position shown in the figure below. (Let w = 225 N, D = 44 cm and d = 5.5 cm.) Please help thank you
A uniform tabletop with a mass of 415kg has a length of 2.50m. A 775kg box is placed 0.800m from one side of the table and a 265kg box is placed 1.80m from the same side of the table. What are the forces from the table legs on the tabletop?

The bar is 10 m long. A mass of a 40 kg placed at a 9m from left end of bar. Where should a 60kg mass be placed to balance the bar?
A balance has a 5.0kg object at 0.5m from the fulcrum, and a 20.0kg object a certain ways in the opposite direction from the fulcrum. Where would the 20.0kg object need to be for the system to be balanced? Suppose you placed the 20.0kg object at 0.5m away from the fulcrum in the opposite direction of the 5.0kg object. This would result in an unbalanced system. Where could you then place a 10kg object to rebalance the system?
