A 2.8kg 40cm diameter disk is spinning at 260 rpm How much friction force must the brake apply to the rim to bring the disk to halt in 2.0s The answer should be in Newtons?
Torque is equal to friction force (F) * radius (r). Torque is also equal to moment of inertia (I) * Angular acceleration (a). Angular acceleration is equal to rotational velocity * 2Pi/time, which is 2 seconds. So, F = IRa/r, or 45.63 Newtons
Why should the pulley be a light as possible as well as nearly frictionless?
A light and nearly frictionless pulley reduces the amount of energy lost in the system due to friction, allowing more of the input energy to be transferred efficiently to the load being lifted. This design maximizes the mechanical advantage of the pulley system, making it easier to lift heavy loads with minimal effort.
Static friction is the friction force that must be overcome to keep an object moving at a constant speed?
Static friction occurs between two surfaces that are not moving relative to each other, whereas kinetic friction occurs when the two surfaces are sliding past each other. Static friction acts to resist the motion of an object and prevent it from sliding.
Why should pulleys be moving freely?
Pulleys should move freely to reduce friction and wear on the system, allowing for smoother operation. A freely moving pulley also ensures that the load is distributed evenly between multiple pulleys, leading to more efficient mechanical advantage.
How can one effectively solve pulley problems in mechanics?
To effectively solve pulley problems in mechanics, one should first identify the forces acting on the pulley system and then apply the principles of equilibrium and conservation of energy. By analyzing the forces and tensions in the ropes or cables connected to the pulleys, one can determine the motion and acceleration of the system. It is important to consider the direction of forces, the mass of the objects involved, and any friction present in the system. Practice and understanding of the concepts of mechanics will help in solving pulley problems efficiently.
Do heavier objects roll down a hill faster than lighter ones?
Rolling is more complicated than falling, because rotational inertia is involved. Without that factor, in an ideal world this is the same as asking if a heavier object falls faster than a lighter one. The answer to that question (again, in an ideal world) is no. In the real world... it might, or it might not, it depends on the exact circumstances. There's no fundamental reason that it should if the objects have similar construction (i.e. moments of rotational inertia), but friction and wind resistance complicate things.

What is the path for the serpentine belt on the 01 Taurus?
should be a sticker on fan shroud Alternator, idler pulley, power steering, a/c, tensioner pulley, crankshaft pulley, water pump this is the order cant upload the picture but when placing the belt on if the pulley has the grooves in it the grooved side of the belt should face the pulley and if the pulley is smooth then the back of the belt faces the pulley
How do you align the timing marks for a 2.2 liter Toyota engine?
Timing mark on the crankshaft pulley (mark should be at zero) must be aligned with the mark on the camshaft pulley (mark should be in the middle of the hole in the pulley).
How do you remove the idler pulley for a 3.8 liter?
Should only be one bolt in the middle of the pulley that releases it.
Where is the water pump on a 1996 ford probe se?
Should be the pulley just above the crankshaft pulley

Where is the water pump located on a Ford Expedition XLT?
The water pump pulley is the pulley right above the crank pulley (the big pulley in the bottom of the engine.) Right above the water pump pulley should be the alternator pulley, which drives the alternator. I'm guessing the water pump is behind the WP pulley. == == == ==
You like cheese with do you know the inertia of fart bubbles?
I feel that if you are looking for the inertia of when you eat the cheese and produce a fart bubble, the inertia should be around 3.14 or Pi. Wouldn't you agree?
