- A car is stuck in the mud. A tow truck puls on the car with the arrangement shown in the figure below. The tow cable is under a tension of of 2,620 N and pulis downward and to the left on the pin at its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut; that is, each is a bar whose weight is small compared to the forces it exerts and which exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tension or compression in each strut. Proceed as followrs. Make a guess as to which way (pushing or pulling) each force acts on the top pin. Draw a free-body diegram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations. From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means the direction…A wheelbarrow with w weight of 150N is used to lift a load with a weight of 900 N. The length from the wheel axle to the center of gravity (COG) of the load is 2 ft, and the distance to the (COG) of the wheelbarrow is 1.5 ft. The length from the wheel axle to the hands is 5 ft. The wheelbarrow is also tilted at an angle of 30 degrees with respect to the horizontal. Calculate the motive force required to hold the wheel barrow3.
