A simply supported beam carries a concentrated load W at its centre. The shear force just to the left of the load is:
+W
−W
+W/2
−W/2
While drawing shear force diagram for a point load, shear force must be calculated:
Only before the load
Only after the load
Only at the load
Just before and at the load
If there is no load between two points on a beam, the shear force diagram between those points will be:
Inclined straight line
Parabolic curve
Vertical line
Horizontal straight line
When a uniformly distributed load (UDL) acts between two points on a beam, the shear force diagram between those points is:
Constant
Parabolic
Inclined straight line
Cubic curve
A cantilever beam carries a uniformly varying load with zero intensity at the free end and maximum at the fixed end. The shape of bending moment diagram is:
Straight line
Triangle
Quadratic parabola
Cubic parabola
The slope of bending moment diagram at any section of a beam represents:
Load intensity
Maximum bending moment
Shear force at the section
Maximum shear force
If UDL acts between two points, the shear force diagram between those points is an inclined straight line.
True
False
For a uniformly varying load between two points on a beam, the shear force diagram is parabolic.
True
False
Assertion (A): At a point load, the shear force diagram shows a sudden jump. Reason (R): A point load causes an instantaneous change in shear force. Choose the correct statement.
Both A and R are true and R explains A
Both A and R are true but R does not explain A
A is true, R is false
A is false, R is true
Shear span is defined as the zone where (a) remains constant.
For a simply supported beam carrying a central point load, the reactions at both supports are ______.
equal
unequal
zero
proportional to span only
If the shear force at a section of a beam is zero, the bending moment at that section is generally (a) .
For a beam carrying a uniformly increasing load, the bending moment diagram varies (a) .
A simply supported beam of span 6 m carries a central point load of 12 kN. Find the reactions and the shear force just on either side of the load. Choose the correct set.
(a)
A simply supported beam of span 8 m carries a uniformly distributed load of 4 kN/m over the entire span. Find the reactions at the supports and the maximum bending moment.
