After a warehouse fire, a straight 30 kg pipe fell from the ceiling and rests against a rough concrete floor at point A and a smooth metal wall at point C. There is one remaining cable attached to the center of the pipe and anchored to the corner of a 7 m high ceiling. Determine the reactions at A and C, and the tension in the cable BD.

hello your question is incomplete attached below is the complete question

answer : Ax = 126.13 N

              Ay = 42.04 N

               Az = 84.09 N

               Cz = 0

               T ( tension ) =  294.3

Explanation:

The Reactions at A and C

Ax = = 126.13 N

Ay =   = 42.04 N

Az =  =  84.09 N

Cz = T - 294.3

     = 294.3 - 294.3 = 0

The Tension in the cable BD

294.3 - T = 0

therefore T = 294.3  

attached below is the detailed solution  

its c i just checked it

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it
