A motor delivers 500hp to the tubular shaft, which has an outer diameter of 2 in. The shaft is rotating at 150 rad/s. 1 hp = 550 ft⋅lb/s.
A) Determine its largest inner diameter if the allowable shear stress for the material is τallow= 25 ksi.
Transcribed Image Text:The image depicts a mechanical assembly showing a shaft and its couplings within a machine component. The primary components include:
- **Shaft:** A cylindrical rod that transmits motion and power.
- **Couplings (A and B):** These are two points where the shaft is supported or connected to other elements inside the machine. Points A and B are likely bearings or other support structures that hold the shaft in place.
- **Measurement:** The shaft portion between points A and B measures 6 inches in length.
- **Base/Platform:** The entire assembly rests on a base or platform, indicating it is a stationary component.
This detailed diagram is useful for understanding the spatial relationships and functional components in mechanical systems.
