Question 20

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A uniform beam AB AB\,AB of length 4 m and mass 20 kg rests horizontally in equilibrium on two supports at C C\,C and DDD, where AC=0.8AC = 0.8AC=0.8 m and AD=3.2AD = 3.2AD=3.2 m.

A child of mass 30 kg stands on the beam at DDD.

Figure for question 3

Find the magnitude of the reaction of the support on the beam at C C\,C and the magnitude of the reaction of the support on the beam at DDD.
