Summarize the important mechanical and physical properties of plastics.

Expert Solution & Answer

To determine

Describe the important mechanical and physical properties of plastics.

Explanation of Solution

Plastic is that material which include synthetic or semi synthetic organic compound in large quantity. Also due to the property of malleability, ability to deform under compressive stress, it can change into solid objects.

The important mechanical and physical properties of plastics are discussed below:

1) This type of material, plastic, has high corrosion and chemical resistant.
2) This type of material, plastic, has low electrical and thermal conductivity.
3) This type of material, plastic, has low density rating.
4) This type of material, plastic, has high strength to weight ratio.
5) This type of material, plastic, has wide range of colors and transparencies.
6) This type of material, plastic, is helpful in noise reduction.
7) This type of material, plastic, has low cost as compared to other type of similar materials.
8) This type of material, plastic, has ease of manufacturing in a wide range of complexities and design possibilities.

Q Derive (continuity equation)? I want to derive clear mathematics.

motor supplies 200 kW at 6 Hz to flange A of the shaft shown in Figure. Gear B transfers 125 W of power to operating machinery in the factory, and the remaining power in the shaft is mansferred by gear D. Shafts (1) and (2) are solid aluminum (G = 28 GPa) shafts that have the same diameter and an allowable shear stress of t= 40 MPa. Shaft (3) is a solid steel (G = 80 GPa) shaft with an allowable shear stress of t = 55 MPa. Determine: a) the minimum permissible diameter for aluminum shafts (1) and (2) b) the minimum permissible diameter for steel shaft (3). c) the rotation angle of gear D with respect to flange A if the shafts have the minimum permissible diameters as determined in (a) and (b).
