Calculate Shaft Radius for Coupling System, 100rpm Rotate

Click For Summary
SUMMARY

The discussion focuses on calculating the shaft radius for a coupling system designed to rotate a perspex cylinder at 100 RPM. The cylinder has a diameter of 6 inches and a width of 1 inch, with 10 grams of sand inside, which has a bulk density of 3000 kg/m³. Key considerations include the orientation of the cylinder and whether the sand will be tumbled, as these factors influence the distribution of the material and the overall design constraints.

PREREQUISITES
  • Understanding of rotational dynamics and RPM calculations
  • Knowledge of volume calculations for cylindrical shapes
  • Familiarity with material properties, specifically bulk density
  • Basic principles of mechanical design related to coupling systems
NEXT STEPS
  • Calculate the volume of the cylinder using the formula for the volume of a cylinder
  • Determine the total weight of the sand and its effect on the system
  • Research the impact of cylinder orientation on material distribution
  • Explore design considerations for coupling systems in rotating machinery
USEFUL FOR

Mechanical engineers, design engineers, and students working on projects involving rotating systems and material handling will benefit from this discussion.

Pls help me calculate the shaft radius of a coupling system that's goin to rotate an prespex cylindrical at 100 rpm by a motor... the dia of cylinder is 6 in and its width is 1 in. the material to be rotated is 10 gm s of sand... bulk density if the sand is 3000 kg per m^3...

Is this a homework problem? Is seems somewhat ill defined, particularly with respect to constraints, e.g. power, stress, materials, . . . .

What is the orientation of the cylinder - horizontal or vertical? That will make difference regarding the distribution of the sand. Is the sand to be tumbled, as in a tumbler/blender.

For starters calculate the volume of the cylinder and the volume of sand.
