Solid Mechanics 2 Marks Question with Answers UNIT -1 1. Define stress. When an external force acts on a body, it undergoes deformation. At the same time the body resists deformation. The magnitude of the resisting force is numerically equal to the applied force. This internal resisting force per unit area is called stress. Stress = Force/Area 2. Define strain When a body is subjected to an external force, there is some change of dimension in the body. Numerically the strain ...

Mickey, age 18, is on a chemotherapeutic antibiotic for a musculoskeletal neoplasm. Which drug do you think he is taking? 1.Cyclophosphamide (Cytoxan). 2.Doxorubicin (Adriamycin). 3.Methotrexate (Rheumatrex). 4.Cisplatin (Platinol). - Doxorubicin (Adriamycin). rationale: The only antineoplastic antibiotic listed is doxorubicin (Adriamycin). All of the other medications are chemotherapeutic agents of other classifications that may be used for musculoskeletal neoplasms. A 13-year-old obes...

Strain - Answer-An alteration in the shape or volume of a soil related to stress. It is calculated as the ratio of the new shape compared to the original shape Effective Stress - Answer-The total amount of stress placed on a soil minus the pore-water pressure Normal Stress - Answer-The component of total stress that acts perpendicular to the plane. Shear stress - Answer-The component of total stress that acts parallel to any point in question. Dilatancy - Answer-Tendency of a materia...
