Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

Two metal bars are fastened together at the bolted flange connection shown. There are 4 total bolts connecting the two metal bars together and each bolt has diameter = 50° with dbolt 12.7 mm. The flange is oriented at angle respect to longitudinal axis of the metal bars. If an axial force F = 40 kN is applied as shown, determine the overall safety factor of the bolted connection. You may assume the bolts are made out of 1020HR steel and the strength of the bolt in shear is 50% of the tensile strength of the bolt material. = F SFO overall = Ө number (rtol=0.01, atol=1e-05) F ?
Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall.
