Question

Which of the following is true about this lever?

Answer 1

As we can see here the lever has two forces at two ends

1. 300 N

2. 200 N

now we need to find the Torque on the lever about the fulcrum

so we will have

1. clockwise torque due to force at right end is

$\tau_1 = d_1F_1$

$\tau_1 = 6(200) = 1200 Nm$

2. counterclockwise torque due to force at left end

$\tau_2 = d_2F_2$

$\tau_2 = 1(300) = 300 Nm$

so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction

so it will rotate clockwise

Answer 2

The lever will rotate clockwise.
