Project

Design a windshield wiper mechanism for a truck as shown in the figure

below. A force $F1$ is applied to lever $1$ by an adjacent link. The reaction

force, $F2,$ on lever $2$ is transmitted to another link. Let the distance, d$,$

between elements is $20\mathrm{.}0mm.$

You are required to design the complete system.

Submit full design calculation, assembly drawing and working drawings. please solve with numbers $-$The weight of the windshield wiper

$-$the friction force between the wiper blades and glass

$-$minimum shaft diameter at section c

$-$lever thickness and width assume any missing data $($its a designning problem$)$
