top of the beam is 8 ft above the ground.
The construction site has some telephone wires crossing it.. The workers are concerned
that the beam may hit the wires. When the beam makes an angle of 60o with the ground,
the wires are 2 ft above the top of the beam. Will the beam clear the wires on its way to
standing up straight? Explain your answer

Question 1202527: The largest truck commonly received is 20m long and can hold 26 pallets of goods. The owner doesn't like to receive partial shipments. The receiving bay therefore needs to be bigger than the area of pallets. You decide to make two rows of 13 pallets each. A forklift is used to move pallets and it requires a width of 2,85m to operate in. Each pallet is 1.25m long and 1.25m wide. What size would the receiving bay area be for two pf palltes and space between rows?
