Question
In a museum exhibit, three equal weights are hung with identical wires, as shown in the figure. Each wire can support a tension of no more than 87.0 N without breaking. The wires are at a 90 degree angle with the support, The first weight is hanging from the support, the second weight is hanging below the first weight, and the third weight is hanging from the second weight. All in a straight line.
What is the maximum value that w can be without breaking any wires?
Under these conditions, what is the tension in the top wire?
Under these conditions, what is the tension in the middle wire?
Under these conditions, what is the tension in the lowest wire?
Explanation / Answer
According to the question provided we need to find the following values.
Part a) What is the maximum value that w can be without breaking any wires?
W + W + W = 3 W = 87.0 N
W = 29.0 N ===PART A)
Under these conditions, what is the tension in the top wire?
W = 87.0 N =====================ANSWER)
Under these conditions, what is the tension in the middle wire?
= 2 * W = 2 * 29.0 N = 58 N =============ANSWER)
Under these conditions, what is the tension in the lowest wire?
W = 29.0 N =========================ANSWER)
