A new dock lift is being used to move delicate computer equipment off shipping trucks. You need to know what the acceleration of the boxes is when the boxes are at dock level.
What is known:
- The bottom loading pistons accelerate horizontally at a constant 0.3 ft/s2.
- The horizontal velocity of the pistons is 0.6 ft/s when the lift is 4 ft high.
- The lifting arms (AC) is 6 ft long.
- Point A and A' are constrained to move
- Point B is constrained to move vertically.
