Which lists the students in order from student whose machine has the least mechanical advantage to student whose machine has the greatest mechanical advantage? Brian, Dipak, Aida, Lian Lian, Dipak, Aida, Brian Brian, Lian, Aida, Dipak Lian, Aida, Dipak, Brian
Answers
Total input and output of everyone have to be added to get the answer as shown below: Brain : 150 + 300 = 450: Lian : 400 + 350 = 750: Dipak :250 + 450 = 700: Aida -:300 + 375 = 675The answer is in the order of :Lian, Dipak, Aida, then Brian.
Machine: A machine is a contrivance by which output can be obtained by applying minimum input.
Mechanical advantage is a measure of the force amplification or advantage can be obtained by using a tool, mechanical device or machine.
The device preserves the input power and simply reduce off forces against movement to obtain a desired amplification in the output result.
The model for this is related to the law of the lever.
Answer:
The correct answer is D.
Explanation:
In order to do that, You need this formula: Mechanical Advantage = Output Force/Input Force.
1. Brian: MA = 300/150 = 2 N
2. Lian: MA = 350/400 = 7/8 or 0.875 N
3. Dipak: MA = 450/250 = 9/5 or 1.8 N
4. Aida: MA = 375/300 = 5/4 or 1.25 N
So, The order is "Lian, Aida, Dipak, Brian" also known as D. Hope this helps.
