Q2. Shrinkage of plastic part?
Ans. 
Shrinkage of plastic part is the reduction in size of a plastic component during cooling after molding.
• Shrinkage occurs due to the cooling process after the plastic part is molded.

• Factors affecting shrinkage include material type, mold design, processing conditions, and part geometry.

• Shrinkage is typically expressed as a percentage of the original dimensions.

• Compensating for shrinkage is important in designing molds an...read more

Q1. Explain stress, strain curve diagram with example?
Ans. 
Stress-strain curve shows relationship between stress and strain in a material under tension.
• Stress-strain curve is a graphical representation of how a material deforms under stress.

• It typically consists of a linear elastic region, a yield point, plastic deformation, and ultimate failure.

• Example: Steel has a high yield strength, so its stress-strain curve shows a steep initial slope.

• Example: Rubber has a low yield stre...read more

Q2. What is DOF? How many degrees of freedom from any object
Ans. 
DOF stands for Degrees of Freedom. It refers to the number of independent parameters that define the configuration of an object.
• DOF is the number of ways a rigid body can move in 3D space.

• For a rigid body in 3D space, there are 6 degrees of freedom - 3 translational and 3 rotational.

• Examples of DOF include linear motion along x, y, z axes and rotational motion around x, y, z axes.

Q1. Explain stress strain curve
Ans. 
Stress strain curve shows the relationship between stress and strain in a material under tension.
• Stress strain curve is a graphical representation of the relationship between stress (force per unit area) and strain (deformation) in a material.

• It typically consists of a linear elastic region, a yield point, a plastic deformation region, and ultimately failure.

• The slope of the curve in the elastic region is the material'...read more
