Answer:
See explanation
Explanation:
Since no figure was given, I'll explain how to theoretically solve this problem.
When a pin is resolved it has 2 reaction forces, one in the horizontal direction and one in the vertical. For this problem you could name these Ax and Ay. These two forces will act where the pin is, with Ax acting in the horizontal direction and Ay acting in the vertical.
When a rocker is resolved, it has one reaction force that acts perpendicular to the surface the rocker is on. This force can be thought of as B and it acts where the rocker is.
If you are determining the value of Ax, Ay, and B you should use static equilibrium and data given on the figure to solve for the reaction forces. The equations for static equilibrium (2D) are ,, and .
Answer:
a) 2
b) 160 lb
Explanation:
A wedge is a triangular tool made up of wood, metal, stone or plastic.
Given that:
length (L) = 6 inches, height (H) = 3 inches and The effort load applied is 80 lb.
a) Mechanical advantage = Length / Height.
Substituting values:
Mechanical advantage = 6 inches / 3 inches = 2
Mechanical advantage = 2
b) Mechanical advantage = Load / effort
Load = mechanical advantage × effort
Load = 2 × 80 lb = 160 lb
