A crane tower is supported at A and is lifting two masses (m ₁  kg and m ₂  kg).The boom BCD is inclined at the angle e from the horizontal. The length of the boom BCD is l ₁  + l ₂  m. Use the gravitational acceleration 9.81 meter per second-square.

Θ = 14° m1 = 30 kg m2 = 39kg l1 = 0.7m l2= 1.1m

Calculate the x- component of the resultant force at A, (F _Ax  )

Calculate the y- component of the resultant force at A, (F _Ay  )

Calculate the magnitude of the resultant moment at A with direction, (M _a  ).
