A workshop crane is lifting a load of 28 kN through a wire rope and a hook. The weight of the hook etc is 15 kN. The rope drum diameter may be taken as 30 times the diameter of the rope. The load is to be lifted with an acceleration of 1.2 m/sec2. Take a factor of safety of 6 and Young's modulus for the wire rope is 80 kN/mm2. The ultimate stress may be taken as 1800 MPa. The cross-sectional area of the rope may be taken as 0.38 times the square of the wire rope diameter. Neglect the effect of impact load. Calculate the diameter of the wire гope.

Question
Transcribed Image Text:A workshop crane is lifting a load of 28 kN
through a wire rope and a hook. The weight of
the hook etc is 15 kN. The rope drum diameter
may be taken as 30 times the diameter of the
rope. The load is to be lifted with an
acceleration of 1.2 m/sec2. Take a factor of
safety of 6 and Young's modulus for the wire
rope is 80 kN/mm2. The ultimate stress may be
taken as 1800 MPa. The cross-sectional area of
the rope may be taken as 0.38 times the square
of the wire rope diameter. Neglect the effect of
impact load. Calculate the diameter of the wire
rope.
