2020-2-24 · The permissible stresses are: Tensile stress = 70 MPa; Shear stress = 50 MPa; Bearing pressure intensity = 25 MPa. The pin is also made of mild steel. The distance from fulcrum to weight of lever is 880 mm and distance between fulcrum and pin connecting valve spindle links to lever is 80 mm. 12.

#### What is a Bearing Stress? How a bolt can experience the ...

The average bearing stress is the force pushing against a structure divided by the area. Exact bearing stress is more complicated but for most applications, the following equation works well for the average, σ b = P/A b. This relationship can be further refined by using the width and height of the bearing area as.

#### Difference between crushing and bearing stress

2017-10-20 · Now, definition says that Bearing stress is a contact pressure between separate bodies. But the pressure always defined normar to the plane hence, bearing stress can be calculated as Here, Value of compressive load will be 20KN(10+10) And area will be the projected area normal to applied load(i.e. thick.×dia.) Crushing stress
