Question $3(30$ pts$)$

The same AUV from question $2$ is being removed after a storm and the coefficient of static friction between the AUV and the truck bed is $0\mathrm{.}36.$ The coefficient of static friction between the tires and the road is $0\mathrm{.}6.$

a$)$ What can be the maximum angle of the incline $($before the AUV slides off$)?(10$ pts $)$

b$)$ If the angle of the incline is $30$ degrees and you have extra straps for securing the AUV, how much force do those straps need to apply to secure the AUV? $(10$ pts$)$

c$)$ If the angle of the incline is still $30$ degrees, what is the force of friction at each tire $(10$ pts $)$
