*"Epoxy Joint"*

*
*
A joint between two slabs A and B is filled with a flexible epoxy that bonds securely to the concrete (see figure). The height of the joint is b = 100mm, its length perpendicular to the plane of the paper is L = 1 m, and its thickness is t = 12 mm. Under the action of shear forces V, the slabs displace vertically through the distance d = 0.05 mm relative to each other. (a) What is the average shear strain γ in the epoxy? (b) What is the magnitude of the forces V if G = 965 MPa for the epoxy?

*1. A point is that which has no part.*

2. A line is breadthless length.

3. The ends of a line are points.

4. A straight line is a line which lies evenly with the points on itself.

5. A surface is that which has length and breadth only.

6. The edges of a surface are lines.

7. A plane surface is a surface which lies evenly with the straight lines on itself.

8. A plane angle is the inclination to one another of two lines in a plane which meet one
another and do not lie in a straight line.

9. And when the lines containing the angle are straight, the angle is called rectilinear.

10. When a straight line standing on a straight line makes the adjacent angles equal to one
another, each of the equal angles is right, and the straight line standing on the other is
called a perpendicular to that on which it stands.

11. An obtuse angle is an angle greater than a right angle.

12. An acute angle is an angle less than a right angle.

13. A boundary is that which is an extremity of anything.

14. A figure is that which is contained by any boundary or boundaries.

Et cetera.
