Answer to Question #79478 in Mechanics | Relativity for syn

Question

A 2000 Kg of a rectangular box (LxBxH) is suspended in pulley at a distance of 300mm (Horizontal Distance) from a wall at a height of 110meter (Vertical Distance). what is the minimum force required to Displace and Hold a hanging object at 10 degree?

Answer 1

The components of the tension force:
T cos⁡θ=mg
T sin⁡θ=F
The minimum force required:
F=mg tan⁡θ=(2000)(9.8) tan⁡10=3500 N=3.5 kN.
