PROBLEM 1: The 1500-kg beam ABC has fixed support at A and connected to beam BD by hinge at B. Beam BD has a mass of 2000 kg and supported by a cable at D. The cable is attached to the 20-cm-diameter pulley at E and pulled vertically at the other end, by tension T. Given: a = 1.5 m; b = 0.9 m; c = 1.8 m d = 0.6 m; e = 1.4 m; θ = 75°. 1. Calculate the required tension to maintain in equilibrium. (ANSWER: 12.830KN) 2. Calculate the moment reaction at A (ANSWER: 28.499) and the total reaction at A. (ANSWER: 22.192). 3. Calculate the vertical reaction at E

Cables

Cables are collections of wires, alternatively referred to as a cord, connector, or plug. They are one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The earliest use of recognizable electrical cable was the early commercialized telegraph lines. These were iron-made and tedious to produce and install cabling.
