Stress strain is a measure of the relationship between the force applied to a material and the resulting deformation. Keplar reaction refers to the principle of action and reaction in mechanics.

• Stress strain is a measure of how a material deforms under a given load.

• Stress is the force applied to a material, while strain is the resulting deformation.

• Keplar reaction states that for every action, there is an equal and opp...read more

Stress is a physiological response to a perceived threat or challenge that triggers the body's fight or flight response.

• Stress can be caused by various factors such as work pressure, relationship issues, financial problems, or traumatic events.

• It can manifest in physical symptoms like headaches, muscle tension, and fatigue.

• Chronic stress can lead to serious health issues like heart disease, depression, and anxiety diso

Torque is calculated by multiplying the force applied to an object by the distance from the pivot point.

• Torque = Force x Distance

• Force is measured in Newtons (N)

• Distance is measured in meters (m)

• Torque is measured in Newton-meters (Nm)

• Example: If a force of 10N is applied to a wrench at a distance of 0.5m from the pivot point, the torque is 5Nm (10N x 0.5m)

BMD for sway frame is a diagram showing the variation of bending moment along the length of the frame.

• BMD for sway frame will have a shape similar to a zigzag pattern due to the presence of sway in the frame.

• The bending moment will be maximum at the points where the frame experiences maximum sway.

• The BMD can be drawn by analyzing the internal forces and moments acting on the frame.
