A rod has a square cross section of (5 x 5) mm. length of the rod is 120 cm. The allowable stress is 400 MPa. After applying the load (F), square section changes to (4.95 x 4.95) mm.
1. What is the type of the load (F), is it tension or compression?
2. What is the longitudinal strain in steel rod?
3. What is the modulus of elasticity of the material of the rod?
4. What is the value of the applied force?
