Question

A car weighing 130 kN when fully loaded
is pulled slowly up a steep inclined track by a
steel cable (see figure). The cable has an effective
cross-sectional area of 490 mm², and the angle a of
the incline is 308.
(a) Calculate the tensile stress σ_t in the cable.
(b) If the allowable stress in the cable is 150 MPa,
what is the maximum acceptable angle of the
incline for a fully loaded car?
