Problem 12.3 A truck is traveling down a long steady grade (0 = 15°) as shown in the figure. The crate has mass mcrate = 500 kg with height H = 1 m and length L = 2 m. The crate rests on the trailer bed and the surface has a static friction coefficient us = 0.4 and a kinetic friction coefficient μK = 0.3. To prevent the load from shifting, the driver must limit his braking. Determine the maximum truck deceleration if the crate does not slide on the trailer bed. mcrate = 500 kg L m H = 1 m 0 = 15° Ans: -2 m/s² ≤ax ≤-1 m/s²

Problem 12.3
A truck is traveling down a long steady grade (0 = 15°) as shown in the figure. The crate has
mass mcrate = 500 kg with height H = 1 m and length L = 2 m. The crate rests on the trailer bed
and the surface has a static friction coefficient us = 0.4 and a kinetic friction coefficient μK = 0.3.
To prevent the load from shifting, the driver must limit his braking.
Determine the maximum truck deceleration if the crate does not slide on the trailer bed.
