2.8-8 A cable with a restrainer at the bottom hangs vertically from its upper end (see figure). The cable has an effective cross-sectional area A = 40 mm² and an effective modulus of elasticity E= 130 GPa. A slider of mass M = 35 kg drops from a height h = 1.0 m onto the restrainer. If the allowable stress in the cable under an impact load is 500 MPa, what is the minimum per- missible length L of the cable?

2.8-8 A cable with a restrainer at the bottom hangs
vertically from its upper end (see figure). The cable has
an effective cross-sectional area A = 40 mm² and an
effective modulus of elasticity E = 130 GPa. A slider
of mass M = 35 kg drops from a height h = 1.0 m
onto the restrainer.
If the allowable stress in the cable under an
impact load is 500 MPa, what is the minimum per-
missible length L of the cable?
