F=M*g
so M=F/g
M=190N/10m/s
m=19kg
Answer:
r₂ = 4.43 r₁
Explanation:
To solve this exercise we must use Pascal's principle that the pressure at a point at a given depth is constant regardless of the body shape.
Let's use index 1 for the smallest plate and index 2 for the largest plate.
P₁ = P₂
pressure is defined
P = F / A
F₁ / A₁ = F₂ / A₂
A₂ / A₁ = F₂ / F₁
They indicate F1 = 40 N and the mass on the large plate is m₂ = 80kg
therefore the body weight is
W₂ = F₂ = m₂g
we substitute
A₂ / A₁ = m₂ g / F₁
A₂ / A₁ = 80 9.8 / 40
A₂ / A₁ = 19.6
the dishes are generally circular
A = π r²
A₂ / A₁ = π r₂² / π r₁²
A₂ / A₁ = (r₂ / r₁)²
we substitute
(r₂ / r₁)² = 19.6
r₂ / r₁ = √19.6 = 4.43
r₂ = 4.43 r₁
Efficiency = Mechanical advantage / Velocity Ratio:
0.60 = M.A./6
MA = 0.6 * 6 = 3.6
The mechanical advantage is 3.6
Mechanical advantage = Force out / Force in
3.6 = 3000/ Force in
Force in = 3000/3.6
Force in = 833.33 N
Answer: 833.33N
If anyone can help me that would be nice it’s one question about The Kohlberg Dilemmas.
