What is the coefficient of friction between steel and sand?
Between 0.194 and 0.306. Source: https://circle.ubc.ca/bitstream/handle/2429/27995/UBC_1989_A7%20R56.pdf?sequence=1
Is a door handle high or low friction?
low
Why is friction useful for bike brakes?
The friction is useful on a bike when you push it.
Why is a wrench with a long handle more effective in turning a nut in comparison to a wrench with a short handle?
Because the long handle allows more leverage to be applied to the nut.
Need an answer please - a 20 N force applied to the handle of a door produces a 44 N output force what is the ama of the handle?
2.2
Which has a greater torque a perpendicular force applied at the end of a wrench handle or an equal force applied in the same direction near the middle of the handle?
the perpendicular force applied at the end of a wrench handle. Because torque= Fd / T = F d cos θ therefore the greater the distance the greater the torque. T=torque F=force d=distance cos=cosine θ=theta
A broom is an example of machine where are the input and output forces applied?
The applied force to the end of the handle is the input force and the output force is when the broom sweeps over the floor.
What type of lever are knives?
The knife is a third class lever. The pressure is applied to the other end of the handle nearest to the blade and the fulcrum is at the end of the handle nearest to the wrist.
A broom is an example of a machine. where are the input and output forces applied?
The applied force to the end of the handle is the input force and the output force is when the broom sweeps over the floor.
What type of wrench handle is required to measure the amount of twisting force that is being applied in tightening a bolt?
RACKETS
How does friction help a rider on a bike because of handle bars?
W/o friction just about nothing would work. Friction is what keeps the tires from rotating around the rims, and the tires from spinning on the ground. W/o friction a bike wouldn't be steerable, as the bike would continue straight forward even whe the wheel is pointinf towards one side.
Explain working and principal of 3 point starter?
