Activity 1.1.1 Wheel and Axle


This is my Wheel and Axle:

Calculate:

Diameter of the Wheel: 64 mm
Diameter of the Axle: 4 mm

Ideal Mechanical Advantage (IMA)
IMA= Diameter(axle/resistance force)/Diameter(wheel/effort force)
IMA= 4 mm/64 mm
IMA= 1/18

Ideal Mechanical Advantage (IMA) when resistance force is applied to the wheel
IMA= Diameter(wheel/resistance force)/Diameter(axle/effort force)
IMA= 64 mm/4 mm
IMA= 18/1

Ideal Effort Force (MA)- Force needed to overcome the known resistance force if the resistance force is applied to the wheel
MA= Resistance Force/Ideal Mechanical Advantage
MA= 0.5 Newtons x 18
MA= 9 Newtons

Actual Mechanical Advantage (AMA)
AMA= Force Resistance/Force Effort
AMA= 0.5 Newtons/15 Newtons
AMA= 0.033

Efficiency of wheel and axle system (E) when the resistance force is applied to the wheel
E= AMA/IMA
E= 0.033/18
E= 0.001852

Examples of wheel and axle:

  1. Steering Wheel
  2. Faucet

Activity 1.1.1 Second Class Lever


This is my second class lever.

Calculate:
Ideal Mechanical Advantage (IMA)
IMA= Distance(effort force)/Distance(resistant force)
IMA= 15 Lego holes/ 8 Lego holes
IMA= 1.875

Ideal Effort Force to overcome the known Resistance Force
MA(mechanical advantage)=Force(resistance)/Force(effort)
2= 1 Newtons/ Force(effort)
Force(effort)= 0.5 Newtons

Actual Mechanical Advantage (AMA)
AMA=Force(resistance)/Force(effort)
AMA= 1 Newtons/ 0.5 Newtons
AMA= 2

Efficiency of the lever system
Efficiency= AMA/IMA
Efficiency= 2/1.875
Efficiency= 1.07

Examples of 2nd Class Lever:

1. Wheel Barrow
2. Broom

Activity 1.1.1 Third Class Lever

This is my third class lever!

Calculations:
Ideal Mechanical Advantage (IMA)
IMA= Distance(effort force)/Distance(resistant force)
IMA= 8 Lego holes/ 17 Lego holes
IMA= 0.47

Ideal Effort Force to overcome the known Resistance Force
MA(mechanical advantage)=Force(resistance)/Force(effort)
 0.43 = 1.5 Newtons/ Force(effort)
Force(effort)= 3.5 Newtons

Actual Mechanical Advantage (AMA)
AMA=Force(resistance)/Force(effort)
AMA= 1.5 Newtons/ 3.5 Newtons
AMA= 0.43

Efficiency of the lever system
Efficiency= AMA/IMA
Efficiency= 0.43/0.47
Efficiency= 0.91

Examples of 3rd Class Lever:


  1. Fishing pole
  2. Tweezers

Activity 1.1.1 First Class Lever


This is my first class lever.

Calculate:
Ideal Mechanical Advantage (IMA)
IMA= Distance(effort force)/Distance(resistant force)
IMA= 13 Lego holes/ 13 Lego holes
IMA= 1

Ideal Effort Force to overcome the known Resistance Force
MA(mechanical advantage)=Force(resistance)/Force(effort)
1= 1.5 Newtons/ Force(effort)
Force(effort)= 1.5 Newtons

Actual Mechanical Advantage (AMA)
AMA=Force(resistance)/Force(effort)
AMA= 1.5 Newtons/ 1.5 Newtons
AMA= 1

Efficiency of the lever system
Efficiency= AMA/IMA
Efficiency= 1/1
Efficiency= 1

Examples of 1st Class Lever:

  1. Seesaw- the folcrum is in the center of the effort force and resistance force
  2. Elbow extension

My First Post: I'm Back For More

I am back for senior year! Kicking off my second year of engineering with Mr. Olson in the 6th period of Principles of Engineering. Welcome to my blog portfolio, have a nice day.

Besides taking apart and building things my greatest hobby is stenciling and graffiti. I use manila folders to create my stencils and I chase graffiti everywhere I go. Here is one of my favorite pictures I have made.

End of Year Project: Mini Train

Using a packet of drawn parts with measurements but no instructions on how to make each piece we built trains on CAD. We got a chance to use resources outside of what we had learned in class. Youtube had a ton of instructional videos that made it really easy to make all 9 parts and then assembling them. I really enjoyed making the train!
 
The wheel of the train: we will need 4

The hitch peg: only need 1

The hitch magnet: we only need 1

The cow catcher: we will only need 1
The train body: we will only need 1
The axel peg: we will need 4

The stack: we will only need 1

The linkage arm: we will need 2
The linkage peg: we will need 4
The FINAL PRODUCT: now that I have finished assembling the toy train I have been working to make a train track for it to go around.

Architecture Capstone Project

We started getting instructions and going over the project three or four weeks ago. Sam and I have paired up and we started our "Magic House". We chose to have Mr. Bucko as our client. Our progress is tracked on the powerpoint below. This was definitely a fun project!
