The stress is given by:-

(1)

The Stress at the Support

(2)

If the cross section is Constant then this is the maximum stress

The Deflection is given by:-

(3)

The Maximum deflection is at the end and is:-

(4)

The Stress is given by:-

(5)

The Stress at the Support.

(6)

If the Cross-Section is Constant then this is the Maximum Stress.

The Deflection at any point is given by:-

(7)

The Maximum Deflection is at the end and is:-

(8)

Between the Fixed End and the Load.

(9)

Beyond the Load the stress is zero
