EXAMPLE 52 Two-dimensional equilibrium Now we will look at an example where several forces are acting on an object, but in this case the forces are not all along the same axis, As shown in Figure 5.2a, a car engine with weight w hangs from a chain that is linked at point o to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that w...

Hanging weight
Two ropes are connected to a steel cable that supports a hanging weight as shown in the figure.1) Draw a free-body diagram showing all of the forces acting at the knot that connects the two ropes to the steel cable.Draw the force vectors with their tails at the knot. The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.2) Based...
