Question

multiple choice 1 point
what is the formula for torque in terms of the applied force and the lever arm?
$\tau=\beta r$
$\tau=fr$
$\tau=ma$
$\tau=fmu$

Explanation:

Torque is calculated by multiplying the applied force \( F \) and the lever arm \( r \). The formula for torque is \( \tau = Fr \). The other options: \( \tau=\beta r \) (where \( \beta \) is not a standard variable for force in torque formula), \( \tau = ma \) (this is Newton's second law for linear motion, not torque), \( \tau = F\mu \) (\( \mu \) is coefficient of friction and not relevant for basic torque - force and lever - arm relationship).

Answer:

\(\tau = Fr\) (the option with \( \tau = Fr \))
