Homework Statement A 24in diameter concrete column, at tenth story of an office building, is supporting the flat roof slab is subjected to a wind uplift load of 50.00kips while carrying a factored compressive force of 120.0kips. the column is 10.00ft long. Assume elasticity of concrete...

When I tried that calculator I plugged different values until come up with 30.2408 meters 4 ATM = 30.2408 The problem is the pressure increase is not a constant, I learn about this long ago in chemistry but I forgot how I did it :(

Can you please show me how?

Can you please elaborate?

This is the question: A scuba diver can withstand pressures up to 4 atmospheres without risk of getting the bends. What is the maximum safe diving depth?

That's exactly how the question is being asked.

Homework Statement A scuba diver can withstand pressures up to 4 atmospheres without risk of getting the bends. Homework Equations What is the maximum safe diving depth? The Attempt at a Solution 4 atmospheric pressure = 40 meters down in water. Thus the maximum safe diving depth...

The moment of inertia for a rod is \frac{1}{12} ML^2

Thank you for asking this question, it is the main thing that drove me to make this post. I think it should be (1/12) times mass times length of both rods ... (1/12)ML. But how about the vertical rods?

Ok, do you see how I did that?

summation of masses times radius square: are (m1+m2+m3+m4+ mass of two rods )(r^2) = (4kg + 2kg + 4kg + 2kg + 0.5kg + 0.5 kg)(0.5 m)^2 = 3.25

Homework Statement Torque = 3 Time = 3.12 s Length of the each rod = 1 m so the radius = 0.500 m mass of each rod is = 0.500 kg M_1 = 4 kg M_2 = 2 kg M_3 = 4 kg M_4 = 2 kg http://imageshack.us/a/img27/5475/qu51.jpg Homework Equations What is the energy of the object (please refer...

I took each piece and put it bottom left corner (x,y) (0,0) origin.

Can you find out CM of the figure without any holes (geometrically)? I think it is (x,y) should be (4,4) right? Can you find out the individual CM of the shapes that fit into the holes (geometrically)? rectangle one is (0.5, 1.25) rectangle tow is (0.25, 1.25) Can you after all this...

I don't have the exact placement for the cutouts. I am positive that the two rectangular cutouts are not the same. I agree with you that they look somewhat same size (the height is the same), but the with is for one is 1 and for the other is 0.5. You can verify that from the diagram provided above.
