2. Match the notions to their definitions:

1. Stress	a) a)The deformation of a body that results from an applied force.
2. Shearing stress	b) resistance to external forces.
3. Compressive stress	c) t c) The total change in the size or shape of a body.
4. Total strain	d) strain caused by equal and opposite pushes F at the ends of the rod.

3. What statements are true or false:

1). Strength of materials is a branch of engi­neering that deals with the melting of materials in response to applied forces.

2). The parts of a bridge, for example, must be soft enough to withstand the various kinds of forces.

3). These applied forces are resisted by internal forces, called stresses, in the beams, columns, cables, and other parts of the bridge.

4). The structural parts are deformed in various ways, including stretching, compressing, shearing, twisting, and bending.

5). Bridge designers do not rely on strength-of-materials data to specify suitable materials for the various parts of the bridge.

6). Stress in a body can be defined as resistance to external forces.
