Problem # p004 |
By how much does the vertical position of point C change if the entire assembly heats up by 100°C ?
Assume that the vertical distance h between the support points for the two cables is unaffected by the temperature change.
NOTE : The angle between beam ABC and the horizontal will be only a few degrees leaving the horizontal distance between the points A, B, and C practically unchanged.
