c-tion ; but, since the wall is smooth, thevertical component can be balanced onlyby an opposite force =P. This verticalcomponent, will be upward, or downward, or zero, accordingto the position of the point C. We shall suppose its positionto be such that the component may be upward, and require… … w.a.c From (c), t= I sin. B Lh Substituting the value of t in (6), = tension of cord. 74 STATICS.
