Q2. Generator size and transformer size
Ans. 
Generator size and transformer size are determined based on the power requirements and load characteristics of the system.
• Generator size is determined by the power requirements of the system, taking into account factors such as peak load, average load, and efficiency.

• Transformer size is determined by the voltage and current requirements of the system, as well as the power factor and impedance of the load.

• It is importan...read more

Q1. Describe the stress strain curves. tell us about hoop stress
Ans. 
Stress strain curves show the relationship between stress and strain in a material. Hoop stress is the stress experienced circumferentially in a cylindrical pressure vessel.
• Stress strain curves depict how a material deforms under stress, showing the relationship between stress (force applied per unit area) and strain (resulting deformation)

• The curve typically consists of three main regions: elastic deformation, plastic...read more

Q2. Tell us about stresses in a thin cylinder
Ans. 
Stresses in a thin cylinder are caused by internal pressure and can lead to hoop stress and longitudinal stress.
• Stresses in a thin cylinder are primarily caused by internal pressure exerted on the walls of the cylinder.

• Hoop stress is the stress in the circumferential direction of the cylinder, while longitudinal stress is along the length of the cylinder.

• The formula for hoop stress in a thin-walled cylinder is given by...read more
