Which of the following is an important safety measure during a power failure?
During a power failure, one of the most critical safety measures is to switch off all machines and electrical equipment. This prevents unexpected hazards when the power supply is suddenly restored. If equipment is left switched on, it may start automatically when electricity returns, which can lead to accidents, injuries, or damage to machinery. For example, rotating machines or cutting tools may start without warning, posing serious risks to nearby workers.
Arrange the following steps in the correct order to draw an equilateral triangle with each side of 35 mm.
1. Join CA and CB.
2. Draw a line and mark AB 35 mm as the side of the triangle.
3. With radius AB and center A and B, draw arcs cutting at C.
4. ABC is the required triangle.
A circuit consists of three resistors; 15 ohms, 10 ohms, and 20 ohms. The 15-ohm resistor is in series with the parallel combination of the 10-ohm and 20-ohm resistors. If a 24 V battery is applied across the circuit, what is the total current flowing through the circuit?
Which of the following is NOT required for estimating materials in preventive maintenance?
If the basic size of the diameter of a shaft is 75 mm and variation limit of +0.02 mm is
given, then its tolerance in mm is:
Identify the rough file grade from the figures given below.
_________ type of preventive maintenance is performed based on actual machine condition rather than a fixed schedule.
In thread cutting, 'BSW' stands for _________________.
If the current flowing through a conductor is 5 A and the resistance of the conductor is 10 ohms, what will be the voltage across the conductor, according to Ohm's Law?
When using a multimeter to measure current, which of the following is correct?
The key difference between a marking gauge and a mortise gauge is:
