Question 42. A single rolling load of 8 kN rolls along a girder of 15 m span. The absolute maximum bending moment will be

8 kN.m
15 kN.m
30 kN.m
60 kN.m

Question 43. If in a pin-jointed plane frame (m + r) > 2j, then the frame is (Where ‘m’ is number of members, ‘r’ is reaction components and ‘j’ is number of joints)

Stable and statically determinate
Stable and statically indeterminate
Unstable
None of the above

Discuss Question

Answer: Option B. -> Stable and statically indeterminate

Question 44. A rigid-jointed plane frame is stable and statically determinate if (where m is number of members, r is reaction components and j is number of joints)

(m + r) = 2j
(m + r) = 3j
(3m + r) = 3j
(m + 3r) = 3j

Discuss Question

Answer: Option C. -> (3m + r) = 3j

(m + r)
m + r = 2j
(m + r)>2j
none of the above

Discuss Question

Answer: Option A. -> (m + r)

m + r – 2j
m + r – 3j
3m + r – 3j
m + r + 3j

Discuss Question

Answer: Option B. -> m + r – 3j

2
3
4
unrestricted

Discuss Question

Answer: Option B. -> 3

Question 48. When a load crosses a through type Pratt truss in the direction left to right, the nature of force in any diagonal member in the left half of the span would

Change from compression to tension
