- Please show me how to calculate where I need to place the stack of bricks on the right side in order for the beam to become balanced? Please refer to image.3. Bob and Tom are on opposite sides of a 12 foot see-saw (teeter totter). Bob weight’s 96.6 pounds.The see-saw weight 75 pounds. Bob is sitting 1.5 feet from the left end of the see-saw. Tom is sitting 2 feet from the right end of the see-saw. The pivot for the see-saw is 6 feet from the left end. The see-saw is in balance horizontally. What is Tom’s weight?A painter climbs a ladder. Is the ladder more likely to slip when the painter is near the bottom or near the top?
- The rock and meterstick balance at the 25-cm mark, as shown. The meterstick has a mass of 1 kg.
