Hello!
Everything you've done so far seems to be correct. However, you need to get rid of the sin. To do this, use s
.
This is known as the inverse of sin, which is where you go from a fraction to the actual angle itself.
When you run
through a calculator, you get about 11.537 degrees, or θ = 11.537.
To verify this, all you need to do is run sin (11.537), and the calculator returns 0.2, which is what we're looking for.
Hope this helps!
Take a lamina with three holes near the periphery of the lamina, now suspend the lamina through them, one by one. Draw a line of equilibrium for each suspension point. The point of intersection of these three lines would be the centre of gravity.
