A preliminary design study is to be conducted for a new radio telescope envisions a triangular receiving platform suspended by cables from three equally spaced 40-m tall towers. The receiving platform has a mass of 25 Mg (mega grams) and is 11m below the tops of the towers. What would be the tension on the cables?

Solution

from the problem,

weight of the platform=mxg=25 Mgx9.81 m/s² =25000 kgx9.81 m/s²=245.25 kN

cables are sharing equally so tension in each cable=245.25/3=27.25 kN
