- The potential energy of a system is described the the expression, At what values of x is this system in equilibrium?A 120-cmcm-wide sign hangs from a 5.3 kgkg , 200-cmcm-long pole. A cable of negligible mass supports the end of the rod as shown in the figure(Figure 1) What is the maximum mass of the sign if the maximum tension in the cable without breaking is 350 NN ? (diagram attached below)Please answer it within 30 minutes. I will upvote!
- A medical technician uses a pair of 0.125m long tweezers to remove a wood sliver from a patient. The technician is applying 5 N of squeezing force to the tweezers. If more than 1/5 lb of force is applied to the sliver, it will break and become difficult to remove. Assume the squeezing force is applied at 90 degrees to the tweezers. What is the mechanical advantage?A uniform meter stick pivoted at its centre, has a 100.0 g mass suspended at the 25.0 cm position. What mass would have to be suspended at the 90.0 cm position for the system to be in equilibrium? Show workings.FA b b Pivot F, In the figure above, 4 forces of equal magnitude act on a uniform thin metal plate. The plate has a hinge (pivot) set up at one corner as shown. Rank the four forces in order, from the least amount of torque to the greatest amount of torque generated about the pivot point. Note: Dashed lines are merely drawing aids.

- ASAP PLEASE, show all work and do all steps (a through c) A horizontal pole of weight wp= 230 N and length L=5.00 m is hinged to a vertical wall on its left end. The pole is supported by a wire that connects the right end to a point on the wall directly above the left end of the pole as shown in the figure. A physics student of weight ws = 620N hangs from the right end (not shown). The wire will break if the tension exceeds 1140 N. a) Draw a Free-Body diagram for the pole. b) What is the minimum height above the hinge (h) that the wire must be attached to the wall to avoid breaking the wire? (m) c) What is the magnitude of the horizontal force that the hinge exerts on the pole? (N)A block, m, , is on a frictionless ramp. A rope is attached to this block. The rope goes over a pulley. The other end of the rope is attached to the ceiling. A second block, m, , is attached to a pulley that hangs from this rope. The pulleys are both massless and frictionless. The setup is shown in the image below. (Use 0 = 30°, m, = 40kg and m, =10kg.) %3D What are the magnitudes of the accelerations of each block? b.

- When the beam in situation is balanced , the Angle between the force and the lever arm 0 degrees. True & falseA 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?Show all steps. 1. A 100-kg nonuniform boom that is 6.0 m long is loosely pinned at the pivot at P. A 600-kg concrete block is suspended from the end of the boom at A, as shown in the figure. The boom forms a 30° angle above the horizontal, and is supported by a 4.0-m cable between points D and B. Point B is 4.0 m from P, and point D is 4.0 m above P. The center of mass of the boom is at point C, which is 2.0 m from P. Assume that all the quantities shown in the figure are accurate to two significant figures. What is the tension in the cable connected between points B and D? 4m 2m 4m L. 2m C 30°
