An engineer needs to know how far a long beam will sag under a load. The table shows some results:

LOAD(N): 1000 2000 3200 4400 5200 6500

SAG(cm): 2.0 4.0 6.6 8.8 10.4 13.4

a) one of the measurements for a sag is wrong.

which? What should the result be?

b)What would be the sag for a load of 4500N?

c)What load would give a sag of 5.2 cm?

d)Would a longer beam sag more or less? Sketch a graph ?
