  3. State  Lami’s theorem with sketch & formula .
  4. Draw FBD of ladder in friction.

11.  Define free body diagram.

12. State the centroid of semi-circle and show it on the sketch.

     4 Marks questions 

1. Calculate tension in the strings AB and BC if a weight of 200 N is attached by two strings as shown in Fig

2. Calculate the reactions offered by planes. Refer Fig. . A sphere weighs 500N is supported by two planes, One plane is vertical and other is inclined at 60° to the horizontal.



3. Calculate the position of centroid from bottom left corner ‘B’ for a retaining wall as shown in Fig

4.  Calculate reactions of beam loaded as shown in Figure

5. Calculate position of centroid for T section as shown in Figure No.  with respect to ‘A’.

6. Locate the center of gravity for the solid as shown in Figure



7.A push of 30 N applied at 30° to horizontal just move the block of weight ‘W’ N. If angle of friction is 16°. Find coefficient of friction, total reaction and weight of block.




8. A block is resting on a rough inclined plane whose inclination to the horizontal is 15°. The force of 11 N applied parallel to the plane on which block is resting will just move it down. If the coefficient of friction between the block and the plane is 0.40, estimate the weight of the block.

9.Calculate coefficient of friction if a block weighing 600 N resting on a rough horizontal plane can be moved by a force of 150 N applied at an angle of 60° with the horizontal.

10. Calculate moment of all forces about point ‘A’ for the force system as shown in Fig
