The platform you and your partner are using to get to the windows is a meter wide and four meters long. You know from hauling the platform out of your truck countless times that it has a mass of 70 kg. It is supported by two cables, one at each end, mounted on-center to prevent the platform from tipping over as it is pulled up the side of the building at a constant speed. If you (mass of 55 kg) are standing on the platform 1 meter from one cable while your partner (mass of 87 kg) is 1.3 meters from the other cable and both of you are half a meter from the side, what is the tension in each cable? Assume the platform has a uniform mass distribution and is of negligible thickness.arrow_forward
- A 24 kg rectangular 4.00 m x 3.00 m rectangular sign is suspended from a horizontal 6.00 m long rod with a 5 kg mass as indicated in the figure. The left end of the rod is supported by a hinge, and the right end is supported by a thin cable making a 30.0° angle with the vertical. Draw a free body diagram and calculate the tension T in the cable. The thin cable breaks if it is pulled by more than 200 N. Show than in the present situation the cable can not support the sign without breaking.

A springboard-type diving board is built from high grade aluminum. This particular board has a mass of 65 kg and is 3.85 m long. 33.8 cm wide, and 5 cm thick. (Aside: Most springboards start thick on one end, then get thinner as it moves to the other end. For this problem, assume the springboard has a constant thickness) One end of the springboard is attached to a hinge. The hinge lets the springboard move up and down, but keeps it from sliding out of place. 1.1 m away from the hinge, the springboard rests on (but is not attached to) a fulcrum. A diver with a mass of 65 kg stands on the far end of the springboard (opposite from the hinge), ready to begin their dive. Hinge Fulcrum Note: the measurements for this problem were taken from the springboards used in the 2016 Summer Olympics, 3 m Springboard event.arrow_forward

You are a design engineer working for the company supplying cranes for the contractors and you have been asked to evaluate the tower design. The crane tower supporting the pulley is designed so that the resultant force from the cable tension running over the pulley is oriented along the tower axis. Note: The tension in the cable is the same on both sides so ||Fill = ||F2l|| = T.arrow_forwardA hungry bear weighing 720 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam.
