Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water. The weight in air is 500 N and 200 N in water. First find the volume of the material using force equilibrium when the block is submerged in water. Then calculate the specific weight of the material.

Calculate uniform load (in addition to self wt.) which will cause the section to begin cracking
a) Determine the total shortening of the pile in terms of F, L, A, and E; b) If F=96 kips, L=40 ft., A=100in2, and E=1.5 x 106 psi, how much does such a pile shorten?
the pressure inside a commercial airliner is maintained at 1.00 ATM. what is the net upward force exerted on a (1.0 m)(200 cm) cabin door if the outside pressure is 0.30 ATM?
Rod AB is bent into the shape of a circular arc and is lodged between two pegs D and E. It supports a load P at end B. Neglecting friction and the weight of the rod, determine the distance c corresponding to equilibrium when a = 43mm and R = 143mm..
