What is a hydraulic system

Simora [160]

Explanation:

Hydraulic systems use the pump to push hydraulic fluid through the system to create fluid power. The fluid passes through the valves and flows to the cylinder where the hydraulic energy converts back into mechanical energy. The valves help to direct the flow of the liquid and relieve pressure when needed

A 1 kg puck sliding on a horizontal shuffleboard court is slowed to rest by 1 point

Citrus2011 [14]

Answer:

miu = 0.31

Explanation:

The friction force is defined as the product of the normal force by the coefficient of friction.

$f=miu*N$

where:

f = friction force = 3 [N]

miu = friction coefficient

N = normal force [N]

The normal force on a horizontal surface can be calculated by means of the product of mass by gravity.

where:

m = mass = 1 [kg]

g = gravity acceleration = 9.81 [m/s²]

$N=m*g\\N=1*9.81$

$N= 9,81 [N]$

Now replacing in the equation above, we can find the friction coefficient.

$miu=3/9.81\\miu = 0.31$
