When slack of an activity is positive

A It represents a situation where extra resources are available and the completion of project is not delayed
B It represents that a programme falls behind schedule and additional resources are required to complete the project in time
C The activity is critical and any delay in its performance will delay the completion of whole project
D Any one of the above

Correct Answer: It represents a situation where extra resources are available and the completion of project is not delayed

When slack of an activity is positive - it represents a situation where extra resources are available and the completion of the project is not delayed.
When slack of an activity is negative - it represents that a program falls behind schedule and additional resources are required to complete the project in time.
When slack of an activity is zero - the activity is critical and any delay in its performance will delay the completion of the whole project.

In a band and block brake, the ratio of tensions on tight side and slack side of the band is (where $$\mu $$ = Coefficient of friction between the blocks and the drum, $$\theta $$ = Semi-angle of each block subtending at the center of drum and n = Number of blocks)
A $$\frac{{{{\text{T}}_1}}}{{{{\text{T}}_2}}} = \mu \theta {\text{n}}$$
B $$\frac{{{{\text{T}}_1}}}{{{{\text{T}}_2}}} = {\left( {\frac{{1 - \mu \tan \theta }}{{1 + \mu \tan \theta }}} \right)^{\text{n}}}$$
