a) calculate the weight of the block, and the spring's stiffness.
b) Write the Forces applied to the block if the sink is filled until the block's top is .05[m] below water surface (ρ=1000[kg/m³]).
c) calculate the Pressure Force on block's top and on block's bottom...
Homework Statement
A spring sticks up from the bottom of the sink, 0.20[m] long ; when a light (ρ=750[kg/m³]) wood block (0.2[m,x]×0.2[m,y]×0.1[m,z]) is attached on top of it, the spring becomes 0.05[m] long.
