math
I don't understand what you did ;> I need v= .... but in answer I can use only q,E,I,L,P sa I have to remove x from this equation.

Next question: Can somebody express this in terms of q,E,I,L,P. d^2v / dx^2 = -(((P/L)*(l-x)^2)/2) / (E*I)

A 3m long balance beam is simply supported with an overhang at each end of a=0.5m. A gymnast weighing 50kg is standing a distance c to the right of support A and a distance b to the left of support B. How does the maximum bending moment in the beam depend on the distance c? ...

Rubber particles, roughly 1mm in diameter, have been added to an epoxy resin to increase its resistance to crack growth. Estimate the Young's modulus of the composite, given that the Young's moduli of the epoxy and the rubber are, respectively, 2GPa and 10MPa, and that...

The energy-separation curve for two atoms, a distance, r, apart is: U(r)=−A/r^m+B/r^n Derive and expression for the stiffness of the bond at the equilibrium spacing, in terms of A, B, m, n, and r0. S=dF/dr at r=r0: This is wrong answer for S: Am/r^(m+1) - Bn/r^(n+1)

You are on a diving board and jump up with a velocity of 4.2 m/s. After 1.5 s you land in the water. Assuming a acceleration of -10 m/s and neglecting air resistance: a) What is your impact velocity? b) How high is the diving platform?
