In summary, the tangential speed of a lug nut on a wheel of a car, located 0.114 m from the axis of rotation, rotating at 6.53 rev/sec is 4.68 m/s. This was calculated by converting 6.53 rev/sec to 4103 rad/s and using the formula Vr = rω, where Vr is the tangential velocity, r is the distance from the axis of rotation, and ω is the angular velocity.

What is the tangential speed of a lug nut on a wheel of a car if the lug nut is located 0.114 m from the axis of rotation; and the wheel is rotating at 6.53 rev/sec?
(a) 0.745 m/s (c) 2.98 m/s (e) 9.36 m/s
(b) 1.49 m/s (d) 4.68 m/s

1) I was able to convert 6.54 rev/sec to 4103 rad/s
2) I don't know if the ratio is what you see on the picture? can you see the picture and let
me know if that is the radio?

Try to think about it this way. What distance does the nut travel per revolution of the wheel? If it makes 6.53 revolutions per second, how far does it travel in that second? So what's the velocity, then?

velocity would be Vr = r.ω

(0114 m)(41.03 rad/s) = Vr
Vr = 4.68 m/s

Thanks!
 

Related to Tangential Speed of Lug Nut on a Car Wheel

1. What is tangential speed?

Tangential speed is the speed at which an object moves along a circular path, tangent to the circle at any given point. It is a measure of how fast an object is moving around the circle, rather than how fast it is moving in a straight line.

2. How is tangential speed different from linear speed?

Tangential speed is different from linear speed because it only measures the speed along the circular path, while linear speed measures the speed in a straight line. For example, a car moving at 60 miles per hour on a circular track will have a tangential speed of 60 miles per hour, but a linear speed of 0 miles per hour since it is not moving in a straight line.

3. How is tangential speed related to the radius of the circle?

Tangential speed is directly proportional to the radius of the circle. This means that as the radius increases, the tangential speed also increases, and vice versa. This relationship is described by the formula v = rω, where v is tangential speed, r is the radius, and ω is the angular velocity.

4. How is tangential speed calculated for a car wheel?

Tangential speed for a car wheel can be calculated by multiplying the angular velocity of the wheel (in radians per second) by the radius of the wheel (in meters). This will give the tangential speed in meters per second. To convert to miles per hour, the tangential speed can be multiplied by the conversion factor 2π/3600.

5. What factors affect the tangential speed of a lug nut on a car wheel?

The tangential speed of a lug nut on a car wheel can be affected by several factors, including the size and weight of the lug nut, the angular velocity of the wheel, and the radius of the wheel. Additionally, any external forces acting on the wheel, such as friction or air resistance, can also affect the tangential speed.
