Q1. What is torque explain with definition
Ans. 
Torque is a measure of the rotational force applied to an object.
• Torque is the product of force and the distance from the point of rotation to the point where the force is applied.

• It is measured in units of force multiplied by distance, such as Newton-meters or foot-pounds.

• Torque is essential in understanding the effectiveness of motors, engines, and other rotating systems.

• Higher torque allows for greater rotational fo...read more

Q2. Strain stress curve and what is yield stress of material
Ans. 
Strain stress curve shows relationship between stress and strain. Yield stress is point where material deforms permanently.
• Strain stress curve is a graph showing how stress (force applied) changes with strain (deformation) in a material.

• Yield stress is the point on the curve where the material begins to deform permanently, even after the stress is removed.

• After yield stress, material may undergo plastic deformation bef...read more

Q4. SFD and BMD for Beams, Simple bending moments formula
Ans. 
SFD and BMD are diagrams used to analyze the internal forces in beams. Simple bending moments formula can be derived from these diagrams.
• SFD (Shear Force Diagram) shows the variation of shear force along the length of the beam.

• BMD (Bending Moment Diagram) shows the variation of bending moment along the length of the beam.

• Simple bending moments formula can be derived from the BMD by analyzing the points where the bendin...read more
