Question:

How do I solve this: If 5 men can do work in 4 days, then how many days does it take 8 men?

Inactive
Harini S.

Problems like these are similar to unitary method problems. When you're asked to see how changing one quantity changes another, 1) Check their relationship. If I increase the number of men, will the number of days increase or decrease? If I had only one chocolate bar (work) and there were five other people, that means my chocolate bar would be eaten way faster! So if I had more men to do the same amount of work, I could finish it in less days! 2) So I know the two quantities are inversely proportional (increasing one decreases the other). When two quantities are direct (increasing one increases the other), you solve it like this: x means y so z means (z*y)/x But if you're inversely proportional, swap x and z sLet's try it: 5 men do work in 4 days Therefore 8 men would need ? days after swapping: 8 means 4 so 5 means (5*4)/8= 20/8=2.5 days Another way to solve inverse problems specifically (the above method would help both types of problems) 5 men need 4 days 1 man would need (5*4) days so 8 men would need (5*4)?8= 2.5 days

Question:

What's the difference between stress and pressure?

Harini S.

When two quantities have the same unit (in this case, Pascal) it's natural to wonder how they differ! Stress and pressure are similar because when we calculate them, we do so by dividing force by area. But stress and pressure differ in terms of direction. Stress can be perpendicular or in any angle. If you push or pull, both can count as stress. But pressure is always perpendicular, and it's always compressive (negative). So pressure is defined as normal force acting against per unit area.
