Q5. The working load limit, WLL, for chains of the same grade, and a range of diameters, are given in Table Q5.

(a) Draw a straight-line graph to verify that the working load limits, W kg, and the chain diameters, d mm, are related by a law of the form W = ad²+b where a and b are constants. (10)

Table Q5

Suggested scales: horizontal axis 2 cm = 100
vertical axis 2 cm = 200

(b) Use the graph drawn in Q5(a) to determine the values of a and b. (6)
