Question

The radial arm saw should be held firmly to regulate the rate of cut, since the saw _________.

Answer 1

The radial arm saw should be held firmly to regulate the rate of cut, since the saw blade moves left and right at a high speed. The speed of the saw blade can be estimated using the information provided about the motor's rotation and the radius of the saw.

Step-by-step explanation:

The radial arm saw should be held firmly to regulate the rate of cut, since the saw blade moves left and right at a high speed. The speed of the saw blade can be estimated using the information provided about the motor's rotation and the radius of the saw. In this case, the motor rotates at 60 Hz and has a radius of 3.0 cm. To calculate the maximum speed, we can use the formula for angular velocity: ω = 2πf

Where ω is the angular velocity and f is the frequency. Substituting the given values, we have:

ω = 2π(60 Hz) = 120π Hz

Now, we can calculate the linear velocity of the saw blade using the formula: v = rω

Substituting the values, we have:

v = (3.0 cm)(120π Hz) = 360π cm/s
