To determine if p4 lies inside or outside the circle with p1, p2, and p3 coordinates.

• Calculate the equation of the circle using p1, p2, and p3 coordinates.

• Check the distance between p4 and the center of the circle.

• If the distance is less than the radius of the circle, p4 lies inside the circle, otherwise outside.

Strength of materials is the study of how materials behave under different forces, while finite element analysis is a numerical method used to analyze complex structures.

• Strength of materials involves studying the behavior of materials under different types of loads, such as tension, compression, and bending.

• Finite element analysis is a numerical method used to simulate and analyze the behavior of structures and components under various conditions.

• Strength of materials helps ...read more

Ratio of radius of inscribed and circumscribed circles of a square of side length a.

• The radius of the inscribed circle is half the length of the side of the square.

• The radius of the circumscribed circle is half the diagonal of the square.

• Ratio of radius of inscribed and circumscribed circles is 1:2.

To find the coordinates of point p1, use the distance formula and the collinearity of the three points.

• Use the distance formula to find the distance between p1 and p2.

• Use the slope formula to find the slope of the line passing through p2 and p3.

• Use the slope and distance to find the equation of the line passing through p2 and p3.

Stress strain curve shows the relationship between stress and strain in a material under tension.

• The curve typically consists of three main regions: elastic deformation, plastic deformation, and fracture.

• In the elastic region, the material returns to its original shape after the stress is removed.

• Plastic deformation occurs when the material undergoes permanent deformation.

• Fracture is the final stage where the material breaks.

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

To determine if a point is inside a circle, calculate the distance between the point and the center of the circle and compare it to the radius.

• Calculate the distance between the point and the center of the circle using the distance formula: sqrt((x2-x1)^2 + (y2-y1)^2)

• Compare the calculated distance to the radius of the circle. If the distance is less than the radius, the point is inside the circle.

• For example, if the center of the circle is (0,0) with a radius of 5, and the p...read more
