SS-V: 1160 Stress Concentration in a Groove Shaft

Test No. VS17 Find the stress concentration in a grooved shaft.

Definition



Figure 1.
The shaft is fixed on one end. A bending moment of 98125 N-mm is applied on the other end. Bending stress is calculated as 1 MPa using the equation below.
σ0=Mc/l
Where,
