A skier is pulled by a rope exerting a horizontal force T=[T] KN at a distance h= [h] cm above the centre of mass (see figure). The skier's body is modelled as one rigid body with a mass m= 80 kg with mass moment of inertia of /=15 kg m² about the centre of mass located above the ski boots. The kinetic friction coefficient between snow and ski is 0.1. The distance d=1 m is between the boot location on the skier and the centre of mass (see figure). Note that load T can cause the skier to slide or tip. Include all handwritten solutions and free-body diagrams. Show all your workings; final results without working will not receive marks. Assume g = 10 m/s². A. Determine the equations to solve the dynamics of a sliding skier at the centre of mass. Justify all assumptions in the used equations. List all unknown variables and number the equations. Solve the equations and analyse the correctness of the sliding assumption. B. Determine the critical load T which causes the skier to tip over during motion. Justify the choice of tipping point. C. Determine the equations to solve the dynamics of a skier on the verge of tipping at an assumed force T-3 kN. List all unknown variables and number the equations. Do not solve the equations. D. Now the situation changes; the skier is holding the rope below the skier's centre of mass at a distance of h=-[h] cm. Determine the critical load T causing the tipping over of the skier.

What is my GPA if I have 5 A's and 1 D

Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…

Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months.   Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.)   Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons.   The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…

Don't need to show work, just need to know which ones correct to compare my answers. 9.10.
