The figure below shows a metal object (2) hanging by a thin cord from a floating wooden block (1). The wood block has a SG of 0.3 and dimensions of 50mm x 50mm x 10mm. The metal part as a volume of 6600m^3. Find the mass of the metal part and the tension in the cord. Work in gage pressure.
Specific weight = W / m^3
Pressure = specific weight X h = pgh
W = mg
The Attempt at a Solution
I find pressure on the point at the bottom of the wooden block - P = 9810 X 0.01
If I am not wrong, that is the tension in the cord ? But I am totally unsure on how to go about solving the mass of the metal part. I suspect that I need to use specific weight = W / V since they gave volume. But how am I suppose to find the specific weight ? Thanks..[/B]
