1. Find the resultant force and moment for (a), (b), and (c), where $\sigma_0$, $\tau_0$, $k$, and $q$ are constants.
$\sigma_x = \sigma_0 \sin\left(\frac{\pi y}{h}\right)$
$\tau_{xy} = \tau_0 \cos\left(\frac{\pi y}{h}\right)$
$\sigma_x = -\sigma_0 \cos\left(\frac{3\pi y}{2h}\right)$
$\tau_{xy} = -\tau_0 \sin\left(\frac{3\pi y}{2h}\right)$
$\sigma_x = ky$
$\tau_{xy} = q(y^2 - h^2)$
