Question: 3 a box weighing 600 lbf is held in place...

Question details

3. A box weighing 600 lbf is held in place on the smooth bed of the dump truck by rope AB as shown in the figure. Neglect friction force between the box and the bed what is the tension in the rope (b) The rope can safely support tensile force up to 350 lbf. Find the maximum allowable an- gle amar the operator of the truck can incline a) For α 15°, . the bed to? (c) The rope AB is replaced with a spring. Find the spring stiffness k such that you allow spring to extend only up to 1 inch when the bed is inclined at angle amaa
