Question

Below are 3 statements about torque and angular rotation. If the statement is TRUE put a + on tho line and if it is false put a 0 on the line The torque caused by a force is given by tau with rightarrow = r rightarrow times F with rightarrow = (r_y F_z - r_z F_y)i -hat + (r_z F_x - r_xF_z)j -hat + (r_xF_y - r_y F_x)k -hat The magnitude of the torque is defined to be tau = rFcos theta where theta is the angle between r withrightarrow and F withrightarrow. The direction on the torque is determined by the left hand rule.

Explanation / Answer

1) true

2) true. is the angle between the position and force vectors

3) false. The direction of the torque can be determined by using the right hand grip rule
