*The resultant couple in pint A will not include the forces acting on the foot and will lead directly to the value of the tension in the rope: The friction in the tires is static and the frictional forces are in the direction opposite to the motion of the truck, because none of the wheels have traction.The resistance of the air was neglected, since the speed must be low.*

Question 1 Calculate the tension 푇 in the cable which supports the 1000 푁 load with the pulley arrangement shown.

The sign of the solution will indicate whether the assumption is correct or not. Equilibrium in 2 Dimensions Basic equilibrium equations: 0, 0, 0 (most commonly used) where A is any point in the plane of the forces. Important Notes When solving equilibrium problems: 1. Choose an equation with the least amount of unknowns (e.g. Practice Problems A force P is applied to a bend rod ACD, which is supported a pin and a roller in 3 different ways. Since the directions of the reactions at A and D are known, we can solve the problem drawing the force triangle.

An alternative set of equations of equilibrium is: 0, 0, 0 where the points A, B do not lie on a line A third possible set of equations of equilibrium is: 0, 0, 0 where the points A, B, C do not lie on a straight line. For each arrangement, determine the reactions at the supports. Example For link BD to satisfy equilibrium, the reaction at D must be directed along DB. The unknown reactions are shown in the positive sense. Apply the equilibrium equations in appropriate order.

Only the 200 N force and A homogeneous cylindrical wooden beam, with diameter of 48 cm, length of 3 m and mass of 100 kg, is hung horizontally by means of two 2 m ropes, as shown in the figure.

The beam is released from rest in the position where each rope makes an angle of 60° with the horizontal.
