The Pictorial diagram shown below shows a landing gear for one wheel of an agricultural aircraft

$($the mass of the aircraft is $1000kg)$ and the front wheels of the aircraft each has $30cm$ diameter

A$-$ Design a suitable a symbolic mechanical system $($don$\text{'}$t use hydraulic system in the design $)$ to

operate two land gears for the airplane shown by labeling all the components.

The appropriate components are to selected by the student taking in consideration all safety$|$

features

B$-$ Make a technical report describing how your system works and why you have selected your

specific components

Part$1$: design evaluation of each element component
