Q1. M15 ratio? In construction
Ans. 
M15 ratio is the mix ratio of cement, sand, and aggregate in construction.
• M15 ratio is commonly used in construction for preparing concrete.

• It refers to the mix ratio of 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts aggregate.

• This ratio is suitable for general construction purposes where high strength is not required.

Q2. Initial setting time of rhc?
Ans. 
Initial setting time of rhc is the time taken for the cement paste to lose its plasticity and become rigid.
• Initial setting time is typically around 30 minutes for ordinary Portland cement.

• It is influenced by factors such as temperature, water-cement ratio, and type of cement used.

• Testing for initial setting time is done using the Vicat apparatus.

Q2. Explain working of Synchronous Motor
Ans. 
Synchronous motor is a type of AC motor where the rotation of the shaft is synchronized with the frequency of the supply current.
• Synchronous motor has a rotor with electromagnets and stator with field windings.

• The rotor rotates at the same speed as the rotating magnetic field produced by the stator.

• It requires DC excitation to create a magnetic field in the rotor.

• Used in applications where constant speed is required, s

Q3. Explain method of Torque Variation of Squirrel Cage Motor.
Ans. 
Torque variation in squirrel cage motors is achieved by changing the rotor resistance.
• Torque in squirrel cage motors can be varied by changing the rotor resistance.

• Increasing the rotor resistance will increase the torque produced by the motor.

• Decreasing the rotor resistance will decrease the torque produced by the motor.

• This method is commonly used in applications where variable torque is required, such as in fans or p
