তাল T b তাল 140 h 7 12/n The above lifting tool is given. The geometric parameters and the coefficient of static friction ?0 between clamp and load are listed below,

the weight G is arbitrary. Calculate the minimum distance x given in the sketch in the unit m(meter) at which the load can just still be lifted. 11=4,5m, 12=4,3m, b=1,7m, a=22,9⁰ μ0=0,65 Important for the calculation: The sketch is not true to scale.
