To determine

The operation of the circuit 2 if contact M1 did not close.

Expert Solution & Answer

Explanation of Solution

Consider the contact M1 is not closed and the current do not flow through the auxiliary contact and to the motor starter, then to the relay coil TR1. Thus, the motor 1 do not operate and the timer delay coil TR1 is DE energized. Since, the de-energized coil fails to close the contact of the TR1 the motor 2 do not starts.

Consider that the motor M2 is in the off state so the timer delay coil TR2 is not energized and the contacts of the TR2 is closed so the motor M3 fails to operate.

Thus, the case when the contact M1 are open the three motors M1, M2 and M3 do not work.

Q Derive (continuity equation)? I want to derive clear mathematics.

motor supplies 200 kW at 6 Hz to flange A of the shaft shown in Figure. Gear B transfers 125 W of power to operating machinery in the factory, and the remaining power in the shaft is mansferred by gear D. Shafts (1) and (2) are solid aluminum (G = 28 GPa) shafts that have the same diameter and an allowable shear stress of t= 40 MPa. Shaft (3) is a solid steel (G = 80 GPa) shaft with an allowable shear stress of t = 55 MPa. Determine: a) the minimum permissible diameter for aluminum shafts (1) and (2) b) the minimum permissible diameter for steel shaft (3). c) the rotation angle of gear D with respect to flange A if the shafts have the minimum permissible diameters as determined in (a) and (b).
