How does the tapered rim of the wheel on a railroad train allow one part of the rim to have a greater tangential speed than another part when it is rolling on a track?

Tangential speed, unlike rotational speed, depends on radial distance. At the very center of the rotating platform, you have no speed at all; you merely rotate. But, as you approach the edge of the platform, you find yourself moving faster and faster. Tangential speed is directly proportional to distance from the axis for any given rotational speed.

Which is greater sliding friction or rolling friction?
sliding friction
Why sliding friction greater than rolling friction and if the area of contact is same?
The FORCE of Friction is INDEPENDENT of Surface Area. Only the 'Coefficient of Friction', and the Force between the two Surfaces. Sliding Friction is greater than Rolling Friction ONLY if the Coefficient of Friction is GREATER for the Sliding Surfaces.
Is the force which prevents the wagon from moving greater than equal to or less than the pull of the engine?
Air friction and rolling resistance
The size of forces due to static sliding and rolling friction between two surfaces?
static sliding has a much greater force then rolling friction cause it covers more area
If a bowling ball and a soccer ball are rolling along the ground at the same speed the bowling ball has more of this because its mass is greater?
Friction

Does hot rolling create greater drafts or does cold rolling?
Yes hot rolling create greater draft than cold rolling . This is because during hot rolling the material is hot due to which it is soft thereby making it easy for more draft
When rolling 2 dice what is the probability of rolling a number greater than 2?
Prob(Rolling a number greater than 2) = 1 - Prob(Not rolling a number greater than 2 on either die) = 1 - Prob(Rolling a number less than or equal to 2 on both dice) = 1 - Prob(Rolling a number less than or equal to 2 on a die)2 = 1 - (1/3)2 = 8/9
A die is tossed. Find the odds against rolling a number greater than 1.?
The probability of rolling a number greater than 1 is 5/6.
What is the probability of rolling a number greater than 4 on a 12 sided die?
Rolling a number greater than 4
What does a baseball rolling along the floor have?
A baseball rolling along the floor has inertia. The amount of inertia depends on the mass of the object. The greater the mass or weight, the greater the inertia.
