People tell me that a straight column wood is stronger than applying weight on a slanted angled wood. It seems like common sense that there's more force applied on an angled wood but when I try to prove it I can't seem to prove it with math.. Please help me.
I am writing a science based report on cantilevers. My question is that,
when I draw designs, does it have to be proportional/scaled if its just in the report as a presentation or does it not matter? I was thinking that becasue my structures are small, 43 cm by 15 cm, I could scale it to fit...
Also, i have another quesiton. I need to write a research report on cantilevers for another class. I need to somehow explain the importance and advantages of cantilevers for the common world. Does anyone have ideas?

for this site.. how do you find the last two numbers of the calculator?
efficiency: Total load that the structure held in grams/ mass of structure.
For the Euler Buckling Formula, I do not understand how to get the compressive load P or I. In example problems, the question gives the value of E and the L. Is the P just the load in N? or do you have to calculuate...
Right now I'm trying to make a cantilever with the highest efficiency. I'm trying to design several models but I have questions:
How can one make one without having to find the best design through numerous times of trail and error? Is there an equation for cantilevers which dictate the...
momentum before and after collision is the same. the only that changes is velocity and the mass in certain cases (as this one) .
momentum is p=mv
conservation equation
mv+mv=mv+mv
okay:
so for the inital momentum of the feula nd rocket i said 0:
0: mv+mv

A solar propulsion engine uses solar power to ionize atoms of xenon and to accelerate them. As a result of the accelerationprocess, the ions are ejected from the spaceship with a speed of 3.0E4m/s
Mass of spaceship is 5.4E2
Engine ejects 7.7E18 ions every second and the fuel mass...
There is a graph saying that at r=1.0 is the center of the moon..
A satellite of mass 1500 kg is launched from the surface of the planet. Determine the minimum kinetic energy at launch the satellite must have so that it can reach the surface of the moon.
The surface of the moon is r=...
A proton of mass m and charge e is acclerated from rest through a potential difference V. The final speed of the proton is: ?
I tried to figure this out.. but I can't find the equation for this.
thank you
