Question

Step by Step Solution ​

Answer 1

Answer:

the loaded beam is stationery upward and downward for us should balance each other

Thus, R+R

′

=40+60=100 kN - (1)

Now the force applied by the beam will be equally distributed among the two supports and the hence the reaction force by the two support will also be equal, i.e, R=R

′

from (1)

2R=100 kN

→R=50 kN

Hence the reaction at support A and B will be equal to 50 kN each.

Answer 2

a) .R+R

40+600=100kn

(1)

from(1 equation)

b). 2R=100KN

R=100/2

R=50kn

has the reaction at support a and b will be equal to each other
