The magnitude of the torque is $~4.0~N\cdot m$

Work Step by Step

In general, the torque is $\tau = r\times F$, where $r$ is the smallest distance between the force vector and the axis, and $F$ is the perpendicular component of the force vector. We can find the magnitude of the torque: $\tau = r\times F$ $\tau = (0.16~m)(25~N)$ $\tau = 4.0~N\cdot m$ The magnitude of the torque is $~4.0~N\cdot m$
