1.5 m
1.5 m
Q16: The thrust bearing consists of a circular collar A fixed to the shaft B.
Determine the maximum axial force P that can be applied to the shaft so that it
does not cause the shear stress along a cylindrical surface a or b to exceed an
allowable shear stress of Tullow = 170 MPa and allowable bearing stress of oallow
300 MPa.
ans.
30 mm 58 mm
35 mm
-20 mm
Q17: In the clevis shown below, find the minimum bolt diameter
and the minimum thickness of each yoke that will support a load P
= 14 kips without exceeding a shearing stress of 12 ksi and a
bearing stress of 20 ksi.
ans.
d = 0.8618 in.
t 0.4061 in
