Question

A wheelbarrow is used to lift a 200 lb loadThe length from the wheel axle to the center of the load is 2ft the
length from the wheel and axle to the effort is 4.5 What is the ideal mechanical advantage

Answer 1

Answer:

That’ll be 4 x 5 and to the max is 3

Explanation:

Answer 2

Calculate:

Ideal Mechanical Advantage (IMA)

IMA= Distance(effort force)/Distance(resistant force)

IMA= 5 feet/ 2 feet

IMA= 2.5

3. Static Equilibrium Calculations:

FE= Force of Effort Force

M= moment (Force x distance)

Moment Effort + Moment Resistance

∑ MFulcrum= 0

(200lbs)(2ft) + (5ft)(FE)= 0

5ft (FE) = 400 lbs/ft

FE= 80 lbs
