3.3.7 - Health and safety question 1

[Maximum number: 2]

A student investigated the bending of a plastic beam.

The beam, of width w and height h, was supported at either end by two metal rods a distance l apart, as shown.

The beam bent downwards as shown.

Figure for Question 3.3.7 - Health and safety question 1 — Edexcel A-Level Physics AS

She measured the vertical distance d moved by the middle of the plastic beam and repeated this measurement for increasing values of F.

She recorded her results in a table, as shown.
