How do you work out the max bending moment for an i cross sectional beam supported at either side with a central force of 20kN?

It actually depends on the type of beam it is. If it is a cantilever, the formula would be PL/2 and for a simply supported beam it would be PL/4

What is the beam bridge weakness?
One of the weaknesses is that because of its design of two beams supported by varied types of supports on either end, it usually cannot be very long, although there are some exceptions.
What is the simply supported beam?
A simply supported beam is just that - the most simple arrangement of the structure. The beam is supported at each end, and the load is distributed in some way along its length. There is more to the application of this than might first appear, but it's the starting point for analysis. What is the load on the beam going to be? If it's a floor joist, how much is the furniture going to weigh that is placed on it? What if someone wants to put a steel safe in the middle of the span of the beam under consideration? You get the picture. But it all stems from a beam supported at the ends and having to bear a load distributed in some way along its length. Simply-supported describes the constraints imposed on the beam by its foundations. A simply supported beam cannot have any translational displacements at its support points, but no restriction is placed on rotations at the supports.

What factors contribute to the electrical resistance of a conductor?
1) What materials the conductor is made of;2) the average cross-sectional area along the length of the conductor;3) the temperature of a conductor also affects its resistance;4) the length of the conductor is also very important.Generally, the longer the conductor, the higher its resistance.Your students' course materials can probably give you a better answer than mine, or at least you'll know it is the right one.The length, the cross sectional area, temperature of conductor along with the intrinsic property called the specific resistance of the substance.
What is an electrical OHM?
A measurement of electrical resistance. It is dimensionally equivalent to Volts / Amperes. (Voltage / Current)AnswerAn ohm is the unit of measurement of resistance. Resistance is not affected by either voltage or current, but by the length, cross-sectional area, and resistivity of the conductor.
What will be change in resistance of a wire if you stretch it?
If you stretch a wire, it would become longer, and therefore thinner. The cross sectional area will decrease and so the resistance will increase. in the real world, if it's stranded wire, the strands will likely break. Solid wire would not stretch evenly, and in either case insulation will tear, so I wouldn't recommend stretching a wire.
What other furniture pieces go with a small sectional sofa?
One option that you have with small sectional sofas are that you can get floating chaise ends, which are ottomans that you can easily move to either end of the sofa.
What term refers to abasic bending movement of the knees in ballet?
That would be either plie or fondue.
What is the political party that supported no laws?
Either Anarchist or Libertarian.
What industryis supported by oceans on either side of Canada?
fishing
What is the mean of 3 29 wire?
3 is the number of conductors and 29 is wire gauge(either in diameter or cross sectional area)
Is bending stiffness for corrugated board applicable for single wall only?
Bending stiffness and Edge crush test values of corrugated board can be correlated to Box crush test values. The Box crush test is one of the values directly used by the engineers in the industry for shipping requirements. SO THIS: "bending stiffness is a basic property of corrugated board it is not limited to single ply or double ply" Bending stiffness is measured using either 2 point, 3 point or 4 point bending stiffness measurement method.
Is Windows 98 Plus still on sale in stores?
No, and its no longer supported by Microsoft either.
Where can I find the best deals on sectional furniture?
After searching the internet I would have to say that like the buffet table, you would need to got to either Leon's or the Brick.
What happens to your biceps muscle when you straighten your elbow?
It either expands or contracts depending on which way you're bending your elbow.
How do you calculate the length and density is given?
If it is normal density you cannot because that is mass/volume. You would need to know either the linear density or the cross sectional area.
Patriotic party that supported the british cause in the revolution?
You can use either term: Loyalist or Tory
Where were the early goldfields discovered in?
Most of the early goldfields were either in central Victoria or central New South Wales.
