Question
Chapter 19, Problem 1RQ
To determine
The recommended repair for a defective relay.
Expert Solution & Answer
Answer to Problem 1RQ
The recommended repair for a defective relay is to replace it.
Explanation of Solution
The relay is a switching device and it works to isolate or change the state of an electric circuit from one state to another state. The classification of the relay is based on its function. The some types of relay are listed below.
- Monitoring relay.
- Protective relay.
- Auxiliary relay.
- Regulating relay.
- Reclosing relay.
These different types of relays have different application in different types of fields such as motor control, electrical fuel pump, in controlling large power loads and high voltage. The most important advantage of the relay is that it takes a relatively small amount of power to operate the relay coil. It can be also used to control the motors, lamps, or heaters.
The relay is manufactured by the magnetic coil which is considered to be a throw away device. Due to the parts in the relay, it is not available for the rebuilding or repairing it. Therefore, the recommended repair for the defective relay is to replace it.
Conclusion:
The recommended repair for a defective relay is to replace it.

Q1: Determine the length, angle of contact, and width of a 9.75 mm thick
leather belt required to transmit 15 kW from a motor running at 900 r.p.m. The
diameter of the driving pulley of the motor is 300 mm. The driven pulley runs at
300 r.p.m. and the distance between the centers of two pulleys is 3 meters. The
density of the leather is 1000 kg/m³. The maximum allowable stress in the
leather is 2.5 MPa. The coefficient of friction between the leather and pulley is
0.3. Assume open belt drive.
5. A 15 kW and 1200 r.p.m. motor drives a compressor at 300 r.p.m. through a pair of spur gears having
20° stub teeth. The centre to centre distance between the shafts is 400 mm. The motor pinion is made
of forged steel having an allowable static stress as 210 MPa, while the gear is made of cast steel
having allowable static stress as 140 MPa. Assuming that the drive operates 8 to 10 hours per day
under light shock conditions, find from the standpoint of strength,
1. Module; 2. Face width and 3. Number of teeth and pitch circle diameter of each gear.
Check the gears thus designed from the consideration of wear. The surface endurance limit may be
taken as 700 MPa. [Ans. m = 6 mm; b= 60 mm; Tp=24; T=96; Dp = 144mm; DG = 576 mm]
