Consider the following beam which is under the action of six forces. The axis of rotation is perpendicular to the beam and passes through the"Pivot".
If the forces are: F = 130 N, F2 = 120 N, F3 =180 N, F4 = 145 N, F5 = 115 N, and F6 = 120 N;
the distances are: a = 3.2 cm, b = 7.4 cm, and c =7.2 cm;
and the angles are: a =20°, and 020°;
• The torque of F isN.m.
• The torque of F2 isN.m.
• The torque of F3 isN.m.
• The torque of F4 isN.m.
• The torque of F5 isN.m.
• The torque of F6 isN.m.
• The direction of F, will be upwards.
• The beam will rotate
• The net torque on the beam isN.m.
• Suppose a wedge is placed 7.0 cm from the Pivot to the right. What minimum force must the wedge exert so that the beam does not rotate?F7 =N.
