1. ### How far will the middle point of the beam sag under load?

There is a wooden beam with given size. We put 1kg in the middle point of beam. Question is how much will the middle point lower itself? Young modulus is 1,18x10^10 Pa Size of beam: length 1 meter , other two dimensions are 5cm and 0,5cm The beam is supported on the ends of it. We...
2. ### Im trying to apply a force at the middle a column, how do i predict the maximum force

Hey guys: Im trying to apply a force at the middle a column, how should i predict the maximum force it will be able to take before break? Here is some data i've got, critical buckling load is P(critical) , the elasticity is 3GN/m^2, standard deviation of that is +2.4/-2.1 MN /m^2. Thanks a...
3. ### Electric Field in Middle Square

I would appreciate it if somebody could assist with the following: Four equal magnitude (4*10^-6) charges are placed at the four corners of a square that is 20cm on each side. Find the electric field at the centre of the square. If the charges have the following sequence around the square...
