Determine the force in members GD, GE, and FD of the space truss and state if the members are in tension orcompression. Determine the force P needed to support the 100-lb weight. Each pulley has a weight of 10 lb. Also, what are the cord reactions at A...Oct 22, 2015 · Certainly then P =75 and/or P=150 must be incorrect for the value of a FORCE. The weight of a 300 kg crate = 2943 N. The value of P should be in N)ewtons . and . there appears to be 3 ropes associated with the load (crate) and three ropes associated with the force = P so wouldn't that mean there is no force advantage?

A winch is used to raise a 500 kg crate at a constant velocity (a = 0 m/s2). Determine the tension in the support arm and the angle theta. Note: the cable that runs from the motor, over the pulley, and to the 500 kg crate is continuous. The picture consists of a motor that has a cable running up to a pulley (which has the 500

Assuming the mass of bicycle plus cyclist is 75 kg, (a) calculate how much work must be done against gravity. (b) If each complete revolution of the pedals moves the bike 5.1 m along its path, calculate the average force that must be exerted on the pedals tangent to their circular path. Neglect work done by friction and other losses. At a UPS distribution center, a 40 kg crate is sliding down an 8° ramp at 3 m/s. At the bottom of the ramp, 8 m away, is a 150 N/m spring designed to bring the crate to rest. The coefficient of friction between the crate and the ramp is (0.2, 0.1). The crate of weight W is suspended from the cable system shown. Determine the force in each segment of the cable, i.e., AB, AC, CD, CE, and CF. Hint: First analyze the equilibrium of point A, then using the result for AC, analyze the equilibrium of...

It is a force provided by the engines which is required to overcome drag (D). The role intended for the aircraft determines the relative position of its main planes, engines, etc. Consider a low-winged aircraft with fixed landing gear and engine mounted on its nose.Find the mass of the object that you wish to calculate the starting or stopping force for. On the earth's surface, the mass of an object is roughly equal to its weight in kilograms, so you can find the mass by simply weighing the object on a scale.
