Answer

Yes Yes

Work Step by Step

$$ M_x=30(0.75)\left(\frac{4}{5}\right)=18 \mathrm{~N} \cdot \mathrm{m}>14 \mathrm{~N} \cdot \mathrm{m}, \quad Y e s $$ $\left(M_x\right)_{\max }$ occurs when force is applied perpendicular to both the handle and the $x$-axis $\left(M_x\right)_{\max }=30(0.75)=22.5 \mathrm{~N} \cdot \mathrm{m}>14 \mathrm{~N} \cdot \mathrm{m}, \quad$ Yes
