Answer:
F= 25/2 = 12.5N
Explanation:
When you use a compound pulley the force required depends on the mechanical advantage of the compound pulley. This is known as rate of loss of distance or the ratio of the force to the load.
M.A = Effort distance /Load distance. OR M.A = Load/Effort
Answer:
The gauge pressure is = 91.52 lb/in²
Explanation:
Given data,
The value of pressure in S.I unit, = 6.31 x 10⁵ N/m²
The conversion formula for SI unit into US Customary Units is given by,
1 N/m² = 1.45 x 10⁻⁴ lb/in²
Using the conversion formula, the new value of pressure becomes,
Pressure = 6.31 x 10⁵ X 1.45 x 10⁻⁴ lb/in²
= 91.52 lb/in²
Hence, the gauge pressure is, ς = 91.52 lb/in²
