Which of the following statements is true? A. Impact loads are equal to the sum of the magnitude of the loads actually caused and the magnitude of the loads had they been dead loads. B. Impact loads are equal to the difference between the above-mentioned entities.
The ability of a material to resist fracture due to high impact loads, is called
Consider the following statements for ductile fracture: 1. The material undergoes substantial plastic deformation with high energy absorption before fracture. 2. Presence of cracks on the surface of material initiates this type of failure. 3. Fracture occurs due to necking. Which of the above statements is/are correct? 
Impact loads are equal to the sum of the magnitude of the loads actually caused and the magnitude if the loads had they been dead loads. State whether this statement is true or false.
According to the fracture theory of the material, the critical value of the crack extension force, which makes the crack propagate to the fracture is called the fracture toughness of the material.

Match the items in column 1 and column 2 and choose the correct combination. Column 1 Column 2 A - Resilience 1 – Ability of the material to return to the original shape when load is removed B – Fatigue 2 – Capacity of a material to absorb energy elastically C – Stiffness 3 – Ability of material to absorb a certain amount of energy without failure D - Elasticity 4 – Resistance of the material to elastic deformation   5 – Failure of material at loads less than that at normal conditions  
When material sustain steady loads for long periods of time, the material may continue to deform until they may tend to fracture under the same load. This phenomenon is known as
