Question
A refrigerator is approximately a uniform rectangular solid 1.9 m tall, 1.0 m wide, and 0.75 m deep.If it sits upright on a truck with its 1.0 m dimension in the direction of travel, and if the refrigerator cannot slide on the truck, how rapidly can the truck accelerate without tipping the refrigerator over? [Hint: The normal force would act at one corner.] A refrigerator is approximately a uniform rectangular solid 1.9 m tall, 1.0 m wide, and 0.75 m deep.
If it sits upright on a truck with its 1.0 m dimension in the direction of travel, and if the refrigerator cannot slide on the truck, how rapidly can the truck accelerate without tipping the refrigerator over? [Hint: The normal force would act at one corner.]
Explanation / Answer
Summation of Torques in the Y direction=mg(width)=ma(height) as Torque equals Force X Radius or Length of the Moment Arm.
Then solve for acceleration as m cancels out. gw/h= 5.16 m/s
