Fig. 3.1 depicts a large sunshade. The labelled features on the diagram are sunshade, arm, pivot, support, and base. The arm carrying the sunshade turns about the end of a support.
(a)[3]
Calculate the weight of the sunshade.
(b(i))[3]
Calculate the moment of the sunshade about the pivot.
(b(ii))[1]
How can the moment produced by the sunshade be made smaller? Tick one box.
Options:
by lowering the height of the support
by reducing the length of the arm holding the sunshade
by making the base heavier
by making the sunshade heavier
