If the allowable stress on the bar is 85 MPa Determine the m

If the allowable stress on the bar is 85 MPa, Determine the magnitude of the maximum load P. What hole location controls the load P? The hole diameter at B = 54 mm

Solution

Load P controls hole B and the area resist the load P will be (130 - diameter )* thickness of bar

So,

Load = stress * area

= 85 *(130-54)*18

= 116.280 KN

So P max is 116.280 KN.
