Question
The figure shows a vehicle jack. In the operating
range, a force analysis is required when 0 = 26°. The
rectangular bars are all the same with L= 350 mm
length, w = 10 mm width and b = 5 mm thickness.
Note that bars are designed pinned ends for buckling
in the front plane.
Calculate the maximum force F (in Newton) for
buckling condition only in front plane (parallel to
plane ABC), knowing that:
Compressive stress yield strength, Sy = 290 MPa
Modulus of elasticity, E = 207000 MPa
Safety factor n = 3.0
