You are going to load a trailer similar to the one below with an aircraft engine that has a mass of 1,017 kg. The length of the trailer from the hitch to the axle is 274 cm. The center of mass of the trailer body is 73.7 cm in front of the axle and it has a mass of 117 kg. If the fraction of weight supported by the hitch can be no more than 119 kg, what is the furthest in front of the axle you can position the center of mass of the engine?

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.

Three identical 8.60-kg masses are hung by three identical springs, as shown in the figure. (Figure 1) Each spring has a force constant of 5.90 kN/m and was 11.0 cm long before any masses were attached to it. Make a free-body diagram for the top mass. Draw the vectors starting at the black dot at the center of the top mass.
A 61.0-kg survivor of a cruise line disaster rests atop a block of Styrofoam insulation, using it as a raft. The Styrofoam has dimensions 2.00 m ✕ 2.00 m ✕ 0.0870 m. The bottom 0.022 m of the raft is submerged. A. Write Newton's second law for the system in one dimension, using B for buoyancy, w for the weight of the survivor, and wr for the weight of the raft. (Set a = 0. Solve for Fy, the y-component of the net force. Let upward be the positive y-direction.) Fy = ( ) = 0 B. Calculate the numeric value for the buoyancy, B. (Seawater has density 1025 kg/m3. Enter the answer to at least the ones digit.) C. Using the value of B and the weight w of the survivor, calculate the weight wr of the Styrofoam. D. What is the density of the Styrofoam? E. What is the maximum buoyant force, corresponding to the raft being submerged up to its top surface? F. What total mass of survivors can the raft support?
A 50 kg pole extends up a wall, making a 60° angle with the wall. The pole is supported by acable attached 3/4 of the way along the pole. This support cable is perpendicular to the wall.A 10 kg sign hangs from the end of the pole. The pole’s center of mass is 1/3 of the way fromthe wall to the end of the pole. (a) What is the tension in the cable?(b) What are the x and y components of the force the wall exerts on the pole?You must include an extended free body diagram showing all forces acting on the pole. Labelthe location on the pole you will use a reference for measuring distances (the “axis of rotation”) at the point where the pole touches the wall. Thank you!
Consider the robotic arm shown below, made up of individual arms AB and BC. The weight of the arms AB and BC are each 160 N, and the resultant weight force is shown to act through each arm's center of gravity as shown.

A hand exerts a force of 125 N on a scale at 30 cm from the joint center at the elbow. If the triceps attaches to the ulna at a 90° angle and at a distance of 3.5 cm from the elbow joint center, and if the weight of the forearm and hand is 45 N with the hand/ forearm CG located 15 cm from the elbow joint center, how much force is being exerted by the triceps?

When one boy is sitting 1.20m from the center of a seesaw, another boy must sit on the other side 1.59m from the center to maintain an even balance. However, when the first boy carries an additional weight of 14kg and sit 1.80m from the center, the second boy must move to 3m from the center to balance. Neglecting the weight of the seesaw, find the weight of the heavier boy. need answer asap
