Stage 2: Development

Historic Foundation: Steve Jobs

Steve jobs is known to have been a great inventor of his time period. He was born in San Francisco, California on the 24th of February, 1955. His biological parents had to have him adopted because of family problems.

He went to school and was a very smart student. Teachers wanted him to skip two classes but his parents only allowed him to advance one class. He was a very successful student and also went to University but he had to drop out.

He started Apple inc. with a friend named Steve Wozniak. After Apple was very successful, Jobs was kicked out of the company by the board of directors. He took a long time off and started another company called neXT. It gained a lot of popularity and was later bought by apple. Jobs also started Pixar and was still owner when great movies like Toy Story were made. It was later bought by Disney.

When neXT was bought by Apple inc, Apple’s business was going very bad so they named Steve Jobs Interim CEO. He the proceeded to make great, revolutionary products like iPod, iPhone, and iPad.

A great way Jobs improved his products and business was his presenting techniques. To find out more, look at the infographic below:

This data shows the force required to pull and hold a laptop in a case on an inclined plane. The force is measured in Newtons. What I got from this data is that more force is required to pull and hold something that is on a steeper inclined plane then a gentle one.  The first one is on a slope of 0.1, the second is 0.35, third is 1, fourth is 1.77, and the last one is 9.8. To conduct this experiment, we used a spring scale, and a shelf board. We measured the rise and run with meter sticks and used the rise over run formula to calculate the slopes.

I hypothesised that if an object is to be pulled up a ramp then it would take more force to pull it up a steeper slope then a gentler one because it is harder to pull something against the force of gravity.

The graph below shows the data in a more visual way. It shows the different tests we did starting from the gentler slopes to the steeper ones.

 

Screen Shot 2013-10-07 at 2.36.23 PM Because of the several tests that were done on the ramps, the data acquired shows that the steeper the ramp is, the more force is required to hold and pull an object over it. It can be seen on the graph, as the slope increases to the right, the force also increases. In the last test, the slope was 9.8, it was around 87o with the floor. As I was doing the experiment, I saw that the holding force was 25 N and the pulling was 27 N. I think that if the slope had a run of 1 cm, then the holding force and the pulling force would be the same.

 

Experimental Journal:

Our method for the experiment was to do different tests on different slopes with the laptop. We first set up the ramp and then measured the rise and run.

In conclusion to my research and results, I found out that it requires more effort force to move an object up a steeper slope than a gentle one because of the force of gravity. The Earth’s gravity pulls all the objects towards it so when an object goes down a slope, like going down stairs, the person is just being pulled by gravity so less force has to be put in by the person itself. But when going up stairs, he/she is carrying their wait against the force of gravity, so more force is required. If the same amount of force as the force of gravity were put when going up stairs, the forces would cancel each other and nothing would happen.  Similarly, going up steeper ramps also requires more force to go up.

It is easier to go up a gentle ramp then a steep one because when going up a ramp, there are two forces applying. One force is the gravity pulling the object down, and the other is the sliding force, the force that makes the object go back down the ramp if it were allowed to. If the ramp were steeper, than the ramp would be high, and the higher the ramp, the more force would act on the object to push down and back. Since a gentle slope is lower, it doesn’t have as much force acting on the objects on it, that’s why it requires less force to move an object over it.
