1.How high does a column of engine oil (unused, 20 deg C) have tobe to give the same pressure as 700 mm of HG at 25 deg C?
2.Does the length of the members in a truss affect the forces inthe joints?
3.A cylinder with a 6 in diameter and 12 in length is put undera compressive load of 138.4 kips. The modulus of elasticity for thespecimen is 6500 ksi and Poissons ratio is 0.4. Calculate the finallength and the final diameter of the specimen under the load.
