Answer
$$
\begin{aligned}
& F=133 \mathrm{~N} \\
& P=800 \mathrm{~N}
\end{aligned}
$$
Work Step by Step
For the handle
$$
\begin{aligned}
M_c=\Sigma M_x ; \quad F(0.03) & =4 \\
F & =133 \mathrm{~N}
\end{aligned}
$$
For the blade,
$$
\begin{aligned}
M_C=\Sigma M_x ; \quad P(0.005) & =4 \\
P & =800 \mathrm{~N}
\end{aligned}
$$
