A cyclist exerts a downward force of F = 90.0 N on a bicycle pedal as seen in the diagram below. If the crank arm is angled 0 = 36.0°

above the x-axis and has a length of l = 25.0 cm, find the torque produced by this force with respect to point O. Find the torque produced by the force with respect to point O. (Define the positive direction to be counterclockwise. Enter the unit as Nm)
