  • Elasticity

    d=diameter of line= 2 m Therefore cross sectional Area of line =pi d^2/4= 3.1416 m^2 1. the stress on the wire Force= 4000 N Stress= Force/Area= 1273.2366 N/m^2 =4000/ 3.1416 2. the strain on the wire strain =

  • Young's Modulus from the slope of the graph and find the error

    Now, we know that the slope of the graph is e/F (this is because we plotted the elongation e on the y-axis, and the load F on the x-axis).
