OBJECTIVE The purpose of this assignment is to experimentally and analytically determine shear forces and bending moments when an external load is applied in various scenarios. In turn‚ we aim to investigate the relative accuracy of such comparisons taking into considerations possible practical applications and possible attributes to the error. Additionally‚ we attempt to develop shear force and bending moment diagrams using MATLAB. Finally we investigate the loadings in a real life situation

Purpose The purpose of this experiment is to test Coulomb’s Law which states that the force between two spherically symmetric charged objects is directly proportional to the product of the charges‚ and inversely proportional to the square of the distance between the centers of the two charges. In mathematical vector notation Coulomb’s Law is expressed as where Fr is the force on particle 1 due to particle 2 in Newtons‚ q is the charge on 12 1 particle 1 in Coulombs‚ q2 is the charge on particle

because of inertia riders continue going at the same speed and direction unless another Force acts on them to change their speed or direction roller coaster cars will gain enough energy from the lift hill to be powered through the rest of the ride. Once put into motion‚ they will not stop until the brakes are applied at the end of the ride. Newton’s Second Law When a roller coaster is going down a steep hill the force of gravity makes the coaster speed up. If they’re kind of higher than the coasters

secured them in two smaller boxes. I secured the eggs in the smaller boxes by rolling a piece of cardboard about an inch in width around the egg to create a holder. The egg can easily slide in out of the holder‚ but not easily enough to fall out once a force is applied. I taped the holder to smaller squares of cardboard and taped them down to the bottom of the smaller box. Each small box had the same construction. Finally‚ to secure the smaller boxes in the big box‚ I hot glued them down in the center

Momentum Running: When running the bases in softball‚ there is a lot more to it then the average person would think. While we run the bases‚ we are changing our momentum by applying more force‚ the force of friction‚ onto the ground which causes more force exerted on us because of Newton’s 3rd law. Applying more force in turn increases the base-runner’s velocity. Catching: When catching a fly ball or grounder‚ it is best to move with the ball and not catch it right over your head or right in front

to figure out the net force and its direction on the Apollo 13 spacecraft as it followed its path. NASA made sure that Apollo 13 would make it back to Earth and not be lost in space. Another scene in which Newton’s Law of Universal Gravitation was needed was when the Apollo 13 crew needed to execute a burn. This law helped them calculate the forces acting on them by other planetary objects‚ and therefore how much force their burn needed to apply. By simply adding together force vectors NASA could predict

If no force is applied‚ no frictional force will be there f frictional force F Applied force From grap it can be seen that when applied force is zero‚ frictional force is zero. 4.

Therefore‚ when the actual time is 2:00 pm on 10 January 2009‚ the time shown on the watch should be 1:51 pm on 10 January 2009.

physics. According to Physics‚ the physical laws of matter‚ energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets‚ molecules‚ atoms or the subatomic particles). Some of the basic pursuits of physics are describing the nature‚ measuring and quantifying of bodies and their motion‚ dynamics and so on. But what I want to touch up on is mass‚ force and weight. Considering that I am a Construction Management major‚ I believe these are
