I need help with this homework. ASAP :

Question $1(50$ points out of a total of $100)$

A long square wooden block is pivoted along one edge. The block is in equilibrium when

immersed in water to a depth of $0\mathrm{.}5$ m as shown in Figure $1.$

Estimate the relative density of the wood $($SGbois$),$ assuming that friction at the pivot

is negligible.

Question. $2(50$ points out of a$.$total of $100)$

The container of water in Figure $2$ has a mass of $20$ kg $.$ Block B has a density of $7840$

$k\frac{g}{m^3}$ and a mass of $30$ kg $.$ Determine the total compression or elongation of each spring

$($Springs C and D$)$ when the block is completely submerged in water.

Note: The spring force can be calculated using the following formula: Fressort $=k|8|$ where k

is the spring constant in $\frac{N}{m}$ and & is the spring travel in m $.$ Fressort is an algebraic value, taken positive in

the case of compression and negative in the case of tension.
