STRUCTURAL ANALYSIS

THE STRUCTURE SHOWN IN THE IMAGE IS

• MECHANISM

• DETERMINANT

• INDETERMINANT

• EXTERNALLY INDETERMINANT

A and B are fixed supports.

If support B settles by 1mm downward, what is direction of rotation at point B?

• +ve

• -ve

• Can’t say

• Depends upon loading at point

fixed end moment formula for point load

• WL²/12

• WL/8

• WL²/10

• WL²/10

The carbon content of steel is:

• Less than 0.15%

• 2% – 4%

• 0.002% – 2.1%

• 0.08%

When carbon contents less than 0.1%, steel is called:

• Mild steel

• Medium carbon steel

• Dead steel

• Hard steel

Very low carbon steel is used for:

• Wires

• Wire nails

• Screw drivers

• Rods
