3. Mechanical advantage may be calculated by dividing the by the MA=R/E __ Solve for the unknown variable in the following problems 4. Weight=400pounds Effort=100pounds MA= 5. Effort=500pounds Weight=250pounds MA= 6. Mechanical advantage of 10. Weight=1000pounds Effort = Effort= 7. Mechanical advantage of 2, Effort of 50 pounds Weight= 8 Dotormine the amount of force required at "B" to balance this lever when 'A' is

Answer 1

1. \( Weight = 400 \) pounds, \( Effort = 100 \) pounds \( MA = \frac{400}{100} = 4 \) 2. \( Effort = 500 \) pounds, \( Weight = 250 \) pounds \( MA = \frac{250}{500} = 0.5 \) 3. Mechanical advantage of 10, \( Weight = 1000 \) pounds \( Effort = \frac{1000}{10} = 100 \) pounds 4. Mechanical advantage of 2, \( Effort = 50 \) pounds \( Weight = 2 \times 50 = 100 \) pounds

Answer 2

Mechanical Advantage (MA) is calculated using the formula \( MA = \frac{R}{E} \), where \( R \) is the resistance (or weight) and \( E \) is the effort. By rearranging this formula, we can solve for the unknown variable in each problem.
