A bucket full of water and weighing 200N is supported by two men holding the handle at each side, each pulling sideways at an angle of 30° to the vertical. Find the force in each man's arm.
At the equilibrium
"mg=2F\\cos30^\\circ"The force in each man's arm
"F=\\frac{mg}{2\\cos30^\\circ}=\\frac{200\\:\\rm N}{2*\\sqrt{3}\/2}=115\\: \\rm N"
