In this experiment, you found the shunt impedance referenced on the

secondary and the equivalent series impedance referenced on the primary side of the transformer.
a. Calculate the equivalent series resistance and reactance reflected to the secondary side of the transformer. (4)
Req’ = Ω
Xeq’= Ω
b. Draw the equivalent circuit with all elements referenced to the secondary side. (4)
8-9
c. Calculate the shunt resistance and reactance reflected to the primary side of the transformer. (4)
Rc’ = Ω
Xm’= Ω
d. Draw the equivalent circuit with all elements referenced to the primary side. (4)

On a average work day more than work place firs are reorted

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
