Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Stokes' law is very important for preparing suspensions. On the subject, tick the correct alternative. A - According to Stokes' law, the larger the particles of solid particles, the greater the viscosity. B - The sedimentation velocity of particles in a suspension is inversely proportional to the diameter of the particles and directly proportional to the viscosity of the medium. C - The Stokes equation was based on an ideal condition, in which irregular particles in a little diluted suspension are deposited with turbulence and collision reinforcement, without affinity for the dispersing medium. D - According to Stokes' Law, the larger the suspended particle size, the greater the sedimentation velocity, considering the other constant factors.
Q1(A) At a carnival, a daredevil rides a motorcycle around and around the "wall of death," a wooden cylinder with vertical walls. The radius of the cylinder is R = 5.0m, and the coefficient of static friction between the motorcycle's tires and the walls is us = 0.90. a) Draw a force diagram for the motorcycle. b) What is the minimum speed at which the motorcycle can ride in a horizontal circle without sliding down to the bottom? Q1(B) An elevator and its load have a combined mass of 1100kg, and is suspended from a strong metal cable. The elevator is initially moving upward at 7.00m/s; it slows to a stop with a constant acceleration in a distance of 20.0m. What is the tension T in the elevator cable during this process?

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
