Simple machines formula

Question 1

MA =

Answer 1

Effort distance ÷ load distance
Or
Load ÷
Effort

Question 2

Load =

Answer 2

MA × effort

Question 3

Effort =

Answer 3

Load÷ MA

Question 4

Effort distance =

Answer 4

LD × MA

Question 5

E × ED is = too

Answer 5

L x LD

Question 6

Work input =

Answer 6

Work output

Question 7

What is LD

Answer 7

50mm÷2 = radis 25mm

Question 8

Find Ed

Answer 8

ED IS 350MM

Question 9

Determine load kgs ÷ 9.81 m/s squared

Answer 9

600×9.81=5886N

Question 10

Ed=350
Ld=25
What is Ma

Answer 10

350÷25=14

Question 11

MA =14
L=5886
What is E

Answer 11

5866÷14 =420.4n

Question 12

Transpose To find E
E×Ed=L×LD

Answer 12

E=(L×LD)÷ED

Question 13

L=160
LD=2
Ed=8
What is effort

Answer 13

MA= ED÷LD
8÷2=4
E=L÷MA
160÷4=40 POUNDS

Question 14

Define inclined plane simple machine

Answer 14

Used to raise load a certain distance vertical distance by moving greater distance with less effort

Question 15

Kg to newton’s

Answer 15

1kg is 9.81 newtons

Question 16

What is Effort in newtons

Answer 16

Ma=ed÷ld=9÷3=3
E=L÷MA 500÷3=166.67KG
166.67×9.81=1635NEWTONS
