suppose the circumference of a bicycle wheel is 2 meters. if it rotates at 1 revolution per second when you are riding the bicyc

kirill115 [55]

Then the speed of the rider is, v = 2m/s

The linear velocity of an object in a straight line is its speed.

The following is the relationship between linear and angular velocity:

v = rω

The circumference of the bicycle wheel is,

2 $\pi$ r = 2

r = 0.318m

The angular velocity of the wheel is,

ω = 1rev/sec = 2 $\pi$ rad/s

Then the speed of the rider is,

v = rω

v = 0.318×2π

v = 2m/s

A force of 10 N causes a spring to extend by 20 mm. Find: a) the spring constant of the spring in N/m

Mars2501 [29]

Answer:

formula used K=F/∆l

∆l is the elongation of the spring

F=10N
∆l=20mm===> 0.02m
K=10N divided 0.02m= 500N/m

Technician A says that one of advantages of a clutch brake is its ability to bring a vehicle to a halt at low speeds. Technician

djverab [1.8K]

Answer:

Option B

Explanation:

The advantage of using a clutch brake is that it is capable of handling high load torque and ensures safety at high rotational speeds.

The motivation behind a clutch brake is to stop or slow the information shaft from turning, enabling the apparatuses to work without pounding/conflicting. This kills harm to non-synchronized transmissions, and limits the exertion required when moving from impartial into first or switch from a halt.
