Homework Statement http://imagebin.ca/img/uzuDsi.jpg and by maximum it means in magnitude Homework Equations I figured the best (easiest/quickest) method would be to draw the shear force diagram. When I originally did this problem I came up with equations for M and V by dividing...

Hi sorry I am rather new to all this but I was woundering if I could get some help? Im currently studdying for my Uni's resits over the summer which fall in just a few weeks time. Iv started to go through some of the old past pappers and I've got stuck on the same bit over and over again...

Homework Statement what is the bending moment formula? is it related to the pure bending formula? what's that? Homework Equations The Attempt at a Solution is the formula 1/p=M/EI?

Can anyone explain in words (or equations if you can't use words, or in words to describe the equations) how "...according to the theory [of gen relativity], half of this deflection [of light by any massive body, the sun in this quote's case] is produced by the Newtonian field of attraction of...

If I were to bend a cantilever by applying a certain amount of force at one end, would the distance it bends in a circle be linearly related to the torque resulting from the force? If not, would there be a measurable difference from being linear if I were to bend a, say, 0.5m long object with...

Hello, not too sure if this is the right section but i do remeber reading it in a book about astrophysics and cosmology. The reason I am asking is that a can't find where i read it. It said something like light bends slightly due to gravity or something like that. There was a man in a...
