Using the specific weight of glycerol as solved. what would be the expected pressure at the base of a 120 cm deep glycerol?

There is a tapering bar of uniform strength. The larger cross-sectional area is 500 mm2. Given that density of material is 2500 kg/m3 and length of the bar is 1 m. The uniform strength is 0.11 MPa. The smaller cross-sectional area for this bar would be cm?.

A liquid compressed in a cylinder has a volume of 1000 cm³ at 2MN/m² and a volume of 993 cm³ at 3.3 MN/m². What is the bulk modulus of elasticity?

Q2)A filament 0.5m long and having a cross-sectional area of 1mm2 was stretched to breaking. If the breaking stress for the filament was found to be 109 Pa, calculate the mass which was hung on the filament to break it. Assuming the filament stretched linearly up to breaking, calculate the amount by which the filament stretched. (Young’s modulus for the material = 6 x 1010 Pa) If the assumption in (b) was justified, what might the material have been? State in one word.
