Criteria of Failure - Factors of Safety

1) Maximum Principal Stress (useful for brittle materials)

2) Maximum Principal Strain (useful for concrete)

3) Maximum Shear Stress (Tresca)

4) Maximum Strain Energy (values required may be obtained from experimentation)

5) Maximum Shear Strain Energy ( Von Mises)

MEP Statics and Dynamics

Distance, Time, Velocity and Acceleration for linear and Angular motion.
The area under the Velocity- Time graph will give the distance travelled in metres.
The gradient of the diagonal line will give the acceleration.

Acceleration= (final velocity-initial velocity)/ time.
