Use the equations you have studied so far in mechanics to tackle the homework problems.
The pyramids in the pictures were built about 4,ooo years ago and 3 ton blocks of limestone had to be dragged horizontally against the force of friction and vertically against the weight force exerted by gravity.
To be handed in tomorrow.
for each question or part question write down clearly and neatly:
the equation you are using
Insert the quantities you are given into the equation on a new line.
finally write down the answer with the correct units on the last line.
Untidy and poorly presented work will NOT be accepted.
You have just taken the first steps to becoming an engineer.
