Question

You are headwaiter at a new restaurant, and your boss asks you to hang a sign for her. Youre to hang the sign, whose mass is

Answer 1

Answer #1

Taking moment about pivot point,

(-mg/2) - (Mg/2) + T sin(phi) = 0

Sin(phi) = (m + M) g/2T

Height, h = 2.3 tan(phi) = 2.3 tan[arcsin ((m + M) g/2T) ]

h = 2.3 tan[arcsin ((51 + 8.3) x 9.8/2 x 720) ] = 1.01 m

Comment in case any doubt please rate my answer....
