Homework Statement
Two 8.0N forces act at each end of a beam of length 0.60m. The forces are parallel and act in opposite directions. The angle between the forces and the beam are 60 degrees.
What is the torque of the couple exerted on the beam?
1. 2.4Nm
2. 4.2Nm
3. 4.8Nm
4. 9.6Nm
Homework Equations
From my understanding: Torque = Fdsinθ, where F is the force and d is the distance from the force
The Attempt at a Solution
I tried to apply the equation (as above) in this example:
Torque = Fdsinθ = 8.0 * .30m * sin(60) ≈ 2.07
However, this isn't one of the given options so I feel I must be doing something wrong.
Any help is greatly appreciated!
