Structural Mechanics Quiz # STM 01

This section consists of quiz covering topics related to an introductory course in Structural Mechanics/Strength of Materials.

 

Select the most appropriate answer for the following questions.

 

1 If the outward normal on an area is in the positive x-direction, and the force acting on it is in the negative z-direction, the stress developed on the area will be

 (i) tensile stress            

 (ii) compressive stress            

 (iii) shear stress

 

 

 

 

2 A force of 40 kN is acting at an angle of 60° to an area of 4 cm2. Calculate the average shear stress on that area.

 (i) 5 MPa                       

 (ii) 50 MPa                             

 (iii) 0.5 MPa

 

 

  

3 A bolt is being used in a lap joint to connect two steel plates which are carrying a tensile force. the stress developed in the bolt will be

 (i) tensile                         

 (ii) compressive                    

 (iii) shear

 

 

  

4 The failure stress of a material was found to be 100 MPa. find the allowable stress if the factor of safety is to be 2.0

 (i) 50 MPa                       

 (ii) 200 MPa                       

 (iii) 25 MPa

 

 

  

5 In a tensile test experiment, the length of a solid cylindrical rod increased from 50 cm to 52 cm. find the average normal strain in the rod.

 (i) 0.25                            

 (ii) 0.04                           

 (iii) 0.002
