The drag coefficient must he determined experimentally. Why?

A steel bar 2 m long, 40 mm width and 20 mm thickness is subjected to an axial pull of 160 kN in the direction of its length. find the changes in length, width and thickness of the bar. take E-200 GPa and poison's ratio=0.3.

Q3. A copper bar of 50 mm*50 mm cross section is 1.5 m long, it subjected to an axial pull of 100 KN. If the value of poisson's ratio is 0.25 and E-100 Gpa, what are the changes in the length, width and volume of the bar?

ces Help Save & Exit The Stokes-Oseen formula for drag force Fon a sphere of diameter D in a fluid stream of low velocity V, density p, and viscosity is F = 3лμDV + pV²D². Is this formula dimensionally homogeneous? Yes or No No Yes

A 35 N plate having a dimension of 3 m by 3 m is sliding on a ramp (slope = 35o ) at a velocity of 3.7 cm/s. The plate and the ramp have a clearance that is filled with a thin film of lube oil with a viscosity of 0.08 Pa-s. Neglecting the edge effects, calculate the clearance between the ramp and the plate. please show a diagram or figure.
