A 2kg weight slides at constant velocity down a plane inclined at 20 degrees to the horizontal, with a 0.5mm oil film ( dynamic viscosity = 0.234 NSm-2) between the weight and the plane. The contact area between the weight and the oil is 10-2 m2 The velocity is

An 79.7 kg skier is gliding on her waxed wood skis down a hill that is at an angle of 12.0 below the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.100. In her upright position, she has a cross-sectional area of A-0.700 m² and a drag coefficient of C-1.00. Assume that the density of the surrounding air is p-1.21 kg/m². Calculate the skier's steady state velocity as she glides (without actively propelling herself) down this hill, accounting for both the friction of her skis and the dragon her body due to air resistance Pse ne numercelanower below Accepted formats are unders based fic rotation ag 022 21 52 Enter answer here. m/s

A vertebra is subjected to a shearing force of 5.0 x 10° N. Find the shear deformation, taking the vertebra to be a cylinder 3.00 cm high and 4.00 cm in diameter. The shear modulus for vertebrae is 8.0 x 1010 N/m. shear deformation:

A plate situated at distance of 7 mm from a fixed plate is moving at velocity of 4 m/s. The gap between the plates is filled with oil with density of 800 kg/m³ and kinematic viscosity of 1,25-10-4 m²/s. What is the shear stress on the surfaces? Round off the answer to an integer in Pa, but enter the answer without the unit. Answer:

A thin rod extends from x =D 0 to x = 13.0 cm. It has a cross-sectional area A = 6.50 cm-. adits density increases uniformly in the positive x-direction from 3.00 g/cm2 at one endpoint to 19.0 g/cm at the other. The density as a function of distance for the rod is given by p B+ Cx,

Problem 11:  Suppose a vertebra is subjected to a shearing force of 540 N.Randomized Variablesf = 540 Nh = 2.9 cmd = 4.3 cm Find the shear deformation in m, taking the vertebra to be a cylinder 2.9 cm high and 4.3 cm in diameter. The shear modulus for bone is 80 • 109 N/m2.

The A-36-steel band is 2 in. wide and is secured around the smooth rigid cylinder. If the bolts are tightened so that the tension in them is 400 lb, determine the normal stress in the band, the pressure exerted on the cylinder, and the distance half the band stretches.

To escape a burning buildingAmold has to jump from a third-story window that is about 10.0 m above the ground. Arnold worried about breaking his leg. The largest bone in Arnold's leg is the femurwhich has a minimum cross-sectional area of about 5 * 10 ^ - 4 m. Arnold has a mass of 79.0 kg. lands in deep snow, then his legs can move about 30.0 cm between the time they first hit the snow and the time he comes to a complete stopWhat is the compressive stress on each femur?

During heavy lifting, a disk between spinal vertebrae is subjected to a 5000-N compressional force. (a) What pressure is created, assuming that the disk has a uniform circular cross section 2.00 cm in radius? (b) What deformation is produced if the disk is 0.800 cm thick and has a Young’s modulus of 1.50 X 109 N/m2?
