Answer:
a. 86.7 Nm
b. b. By making sure her foot is on the outermost edge of the pedal aat all times
Explanation:
a. Torque = force * perpendicular distance
= (52 kg * 9.81 m/s²) * 0.17 m
= 86.7204 Nm
b. Torque can be increased by increasing the force exerted peperndicular to the distance from the fulcrum or by increasing the distance itself. Since the person cannot increase their weight, they have to maximize the distance from the fulcrum
The maximum torque is 86.7204 Nm and the rider can increase this by putting int leg on the edge of the paddle.
What is Torque?
It is defined as the force that causes the rotation of an object on an axis. It is measured in Nm.
[tex]\tau = rF\sin\theta[/tex]
[tex]\tau[/tex] = torque
[tex]r\\[/tex] = radius
[tex]F[/tex] = force = mg = (52 kg x 9.81 m/s²) = 510.12 N
= angle between F and the lever arm
Torque = force x perpendicular distance
Put the values,
Torque= 510.12 N x 0.17 m
Torque = 86.7204 Nm
B) Since the torque is directly proportional to the force and perpendicular distance. Hence, the rider must increase the perpendicular distance in order to increase the torque.
Therefore, the maximum torque is 86.7204 Nm and the rider can increase this by putting int leg on the edge of the paddle.
