Asimple curve is to be laid out so that its middle ordinate
is at least 75ft.
if the tangents intersect at an angle of 40 degrees, what is
the highest degree of curve that can be used?

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
