Force 1 and 2 are applied to a beam as shown in the figure. Assume the rotational axis passes through point and perpendicular to the page. F1 F2 d 01 60° 02 L 50° 4.0 m 300 N 220 N 2.0 m F L F2 a) (10%) Find the distance between the rotational axis and the force 1 acting point. b) (10%) Find the angle between the the force 1 line and the line from rotational axis to the force 1 acting point.
