Edexcel IGCSE Physics Scale Diagrams

Diagram 1 shows the apparatus a student uses to investigate the bending of a wooden strip.

Part of the wooden strip is clamped to a table.
A load is fixed to the free end of the wooden strip, causing it to bend.

The free end of the wooden strip is positioned a length, L , beyond the edge of the table, as shown in diagram 1.

The weight of the load causes the end of the wooden strip to move down through a height, h.

A student investigates how the length, L , affects the height, h .

The table shows the results of the investigation.

Diagram 2 shows the wooden strip when $\mathrm{L}=80 \mathrm{~cm}$.

Using diagram 2, determine the height, h, in the laboratory.
[1 cm on the diagram = 10 cm in the laboratory]
height, h=
cm
