In summary, the machine part ABC is supported by a frictionless hinge at B and a 10 degree wedge at C. The coefficient of static friction is .20 at both surfaces of the wedge. Using the equation (-by*10)+(-120*8)=0, the by component is found to be 96.0 lb. However, the components of bx and the force P required to move the wedge to the left are still unknown.

the machine part ABC is supported by a frictionless hinge at B and a 10 degree wedge at C. Knowing that the coefficient of static friction is .20 at both surfaces of the wedge, determine (a) the force P required to move the wedge to the left, (b) the components of the corresponding reaction at B.

I have the by component which is found by (-by*10)+(-120*8)=0 and by= 96.0 lb but I am totally lost on how to get bx and the P force

Welcome to the PF.

A sketch of the situation would be most helpful here...
 

Related to How to Determine the Force P Required to Move a Wedge to the Left?

1. What is a wedge?

A wedge is a simple machine that is typically made of metal or wood and has a triangular shape. It is used to split or lift objects by applying force to the wedge's sharp edge.

2. How does moving a wedge to the left differ from moving it to the right?

Moving a wedge to the left means applying force to the left side of the wedge, which will cause it to move in the opposite direction (to the right). This is because of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.

3. What are some common applications of moving a wedge to the left?

Some common applications of moving a wedge to the left include splitting wood, cutting food, and lifting heavy objects. It is also used in construction and manufacturing processes.

4. How does the angle of the wedge affect its effectiveness when moving it to the left?

The angle of the wedge can greatly affect its effectiveness when moving it to the left. A sharper angle will require less force to move the wedge, but it may not be as stable. On the other hand, a wider angle will require more force to move the wedge, but it will be more stable and less likely to slip.

5. Can moving a wedge to the left be used as a method of propulsion?

Yes, moving a wedge to the left can be used as a method of propulsion. This is seen in tools such as axes, where the wedge is moved to the left and then quickly pulled back to generate enough force to cut through an object. It is also used in some forms of transportation, such as ice skates and sleds.
