SUMMARY

The discussion focuses on calculating the tension and acceleration in a two-block pulley system involving a 22.7N block on an inclined plane at a 17.2-degree angle and a 34.5N hanging block. The coefficient of friction for the inclined plane is 0.219. The key equations derived include the net force equation for the hanging mass, expressed as mg - T = ma, and the need to analyze forces acting on both blocks to determine their acceleration and the tension in the string. The same acceleration applies to both blocks due to the single rope connection.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of forces, including tension and friction
  • Familiarity with inclined plane dynamics
  • Ability to perform vector decomposition of forces
NEXT STEPS
  • Calculate the net force acting on the hanging block using Fg = mg
  • Determine the frictional force acting on the block on the inclined plane
  • Analyze the components of weight acting along and perpendicular to the inclined plane
  • Explore advanced pulley system dynamics and tension calculations
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the mechanics of pulley systems and inclined planes.

consider the two body system above. a 22.7N block is placed upon an inclined plane which is inclined at a 17.2 degree angle. The block is attached by a string to a 34.5N block which is suspended over the pulley. the coefficient of friction( arrow pointing) is 0.219.

Determine the acceleration of the block and the tension in the strings

Hi moe6142, welcome to PF.
Since the single rope is connecting the two masses, they must have the same acceleration. And tension in the two segments of the string must be the same.
Now find out the forces acting on each mass and find the acceleration.
 
the Force of tension and gravity are acting upon the hanging object

Fg on the hanging block would be 34.5N

since i am trying to find acceleration, so i have to find the Fnet .. how would i do that
 
For hanging mass
mg - T = ma.
Now find the forces acting on the mass placed on the inclined plane.
What is the frictional force? What are the components on weight along the inclined plane and perpendicular to the plane?
