Slider Crank Magnitude and Direction of Force on Member AB

Click For Summary
SUMMARY

The discussion focuses on analyzing the magnitude and direction of forces acting on member AB in a slider-crank mechanism. Key insights include the use of acceleration diagrams to determine the forces acting on the piston and connecting rod, with specific emphasis on the trigonometric relationships that define the force components. The analysis reveals that the connecting rod's angle relative to the piston travel direction results in distinct force components acting on point A, crucial for understanding the dynamics of the mechanism.

The acceleration diagram gives you the acceleration of the various bits. You also have the masses. The rest is trig. For example, the piston is accelerating in a straight line. Because the connecting rod is at an angle to the direction of piston travel there is a force component perpendicular to the direction of piston travel and another along the direction of piston travel. Those forces act on A in the direction along the connecting rod.
