- Homework Statement
- A triangle is suspended from the center of mass located at point O and has four 2 Kg mass suspended at

points A, B, C and D. The angles to points A, B, C and D are measured from the horizontal through the

center of mass where θA = 30 ̊ below, θB = 20 ̊ below, θC = 60 ̊ above and

θD = 80 ̊ above. The distances from point O to points A, B, C, and D are

20 cm, 35 cm, 15 cm and 30 cm respectively. Determine the net torque

acting about the center of mass.

- Relevant Equations
- T = F × r × sinθ

Net torque = 2gx20xcos30 - 2gx35xcos20 - 2gx15xcos60 + 2gx30xcos80

= -357Nm

Have I done it right?
