2.8 Project Task: Dimensions of a Shaft
For a shaft subjected to deflection only, as shown in Figure 2.8, the minimum diameter, static deflection, and critical rotational frequency need to be calculated. The load caused by twisting (torsion) can be neglected.
Figure 2.8 Deflected Shaft
Given is the mass of the load ma = 1 kg, the modulus of elasticity E = 216 ⋅ 103 N/mm2, the length of the shaft l = 120 mm, and the maximum permissible bending stress 
= 100 N/mm2.
The minimum diameter d, the static deflection 𝑓, and the critical rotational ...
