Question

The two wires are connected together at A. If the force P causes point A to be displaced horizontally 2 mm. determine the normal strain developed in each wire. The rubber band of unstretched length 2r0 is forced the frustum of the cone. Determine the average

Answer 1

Step-by-step explanation:

For the first question, the normal strain developed in each wire is given by the following equation:

Strain = (Displacement/Original Length) x 100

Therefore, the strain in each wire is:

Strain = (2mm/2r0) x 100 = 100 mm/r0

For the second question, the average developed in the rubber band is given by the following equation:

Strain = (Change in Length/Original Length) x 100

Therefore, the average normal strain in the rubber band is:

Strain = (Change in Length/2r0) x 100

Where Change in Length is the difference between the length of the rubber band after it is forced into the frustum of the cone and the original length of the rubber band.
