The three load contacts connected between the three-phase power line and the motor close to connect the motor to the line. The normally open auxiliary contact connected in parallel with the two Start buttons closes to maintain the circuit to M coil when the Start button is released.
Answer:
Explanation:
Given Parameters
Mass of slender, m = 15kg
Length of AB, a = 4.5m
Initial velocity of slender, = 0m/s
we draw the initial condition of slender as shown in the attached file 1
Now consider the instantaneous center at C
Write the expression to calculate the kinetic energy at initial position ()
substitute the values in the above expression
Write the expression to calculate the Potential energy at initial position ()
here, is the position of the center of mass in initial position
Substitute the values in the above expression
= 331.088Nm
the condition of the slender at the final position is as shown in the second file attached
