Answer:
When inertia increases, it's because the mass increased, which increases the normal force, which ultimately increases friction.
Answer:
Explanation:
Given mass of grindstone 
radius of stone 
angular speed of disc 
Steel Axle applying a force of 
coefficient of kinetic friction 
Frictional Torque applied by steel is given by
where 
=frictional force
Torque is also given by
where 
=angular acceleration
I=moment of Inertia
Answer:
10cm^3
Explanation:
Given data
Mass of steel = 80grams
density of steel= 8 g/cm^3
We know that the formula for density is given as
density= mass/volume
make volume subject of formula
volume= mass/density
volume=80/8
volume= 10cm^3
Hence, the volume 10cm^3
