Types of conveyors and belts include roller conveyors, belt conveyors, chain conveyors, screw conveyors, and vibrating conveyors.

• Roller conveyors use rollers to move items along a path.

• Belt conveyors use a belt to transport materials.

• Chain conveyors use chains to move products.

• Screw conveyors use a helical screw blade to move bulk materials.

• Vibrating conveyors use vibrations to move materials along a trough.

Allowable stress values vary depending on the material and type of loading (tension, compression, shear).

• Allowable stress values are typically provided by material specifications or codes.

• For example, for structural steel in tension, the allowable stress might be around 0.6 times the yield strength.

• In compression, the allowable stress might be lower than in tension due to buckling considerations.

• For shear, the allowabl...read more
