That would be 125(C)=3000. That means that they could make 125 modern rocking chairs and have no lumber left. Now they could also make 100(f)+125(c) and have just enough lumber. By looking at the graph we can see that all they could make and still have enough lumber is any amount within 200 to 250 ranges. Anything outside the range cannot be made using the lumber that the company has on hand.
2014. Retrieved from: http://www.britannica.com B. Compare and contrast electric force and magnetic force. B) With Electric force movement is the key, unlike magnetic force where it exists with stationary charges. With Magnetic force no movement is necessary in contrast to electric force.
The string is tied onto a thin metal bar at A and fixed at B. A vibration generator causes the bar to oscillate at a chosen frequency. Explain how a stationary wave is formed. Then describe the key features of the stationary wave shown in Figure 4. * Waves reflect off the clamp and the rod * Waves travelling in opposite directions superpose * Waves have same wavelength and frequency, similar amplitude * Always cancellation at nodes and constructive superposition at antinodes * Energy is not transferred along string * 4 nodes where there is zero amplitude * 3 antinodes where amplitude is maximum * Wavelength 0.80m * End antinodes in phase and middle and ends in antiphase * Between node and antinode, amplitude of oscillation increases On her next jump the gymnast decides to reach a height above position B.
The results came out to be complete vectors with the corresponding degrees of the angles with we experimented on. II. Theory: The objective of this lab is to understand the principles of force vectors and how they relate to equilibrium. In a perfect system the vectors would add up and be exact to the degrees we calculated, the masses would all be balanced at equilibrium and when adding the vectors together each vector should be connected. This would only apply in a perfect system or when calculating the vectors rather then finding them in real life.
The classic chair requires 15 feet of maple wood so I will use “15x” as the first term of the inequality. The modern rocker requires 12 feet of maple wood, so the term used will be “12y”. The company is able to use 3,000 feet of board to design chairs,
This has to do with the fact that only one out of every twenty homes in Britain has hand-guns, compared to one out of every two in the U.S. This cultural difference is why attempts at gun control in the United States are such a heated topic. Bans and background checks are considered attacks
The second theorem is simply Newton’s third law where air is forced downward so there is a reaction of the airfoil being pushed upward (lift). On a symmetrical airfoil there can be no moment developed about the CP, and do not generate pitching moments at any AOA. This also means that the CP does NOT move with a change in AOA for a symmetrical airfoil. In a cambered airfoil the CP moves along the chord line with a change in AOA, as the AOA increases the CP moves forward and vice versa. The pitching moment at the AC will be constant with changing AOA if velocity is constant.
The maximum frictional force that must be overcome before movement is able to begin is μsFN. If you apply a constant force to pull an object along a horizontal surface at a constant speed, then the frictional force opposing the motion is equal and opposite to the applied force, Fp. Therefore, Fp = Ff. The normal force is equal and opposite to the object’s weight when the object is on a horizontal surface and the applied force is horizontal. The question to be answered by performing this lab is how can the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
In his first law he explained that. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.In second law he define the force and give the expression F=ma where m is the mass of the body and a is acceleration due to gravity. While in his third law he showed reaction that is F12=-F21 which mean in between each two bodies there is equal and opposite reaction. On the other words it mean that if a person is walking that means he is applying force on earth;whereas,earth also applying force on his foot as much he apply on the
