    A block of mass 200kg is being pulled up by men on an inclined plane at angle of \[45{}^\circ \] as shown. The coefficient of static friction is 0.5. Each man can only apply a maximum force of 500N. Calculation the number of men required for the block to just start moving up the plane:

    A) 10  

    B)                           15     

    C) 5                     

    D) 3

    Correct Answer: C

    Solution :

    In a transformer \[\frac{{{n}_{p}}}{{{n}_{s}}}=\frac{{{V}_{S}}}{{{V}_{P}}}=\frac{{{I}_{S}}}{{{I}_{P}}}\] \[\frac{{{n}_{p}}}{{{n}_{s}}}=\frac{1}{2},{{V}_{P}}=1.5\] \[\frac{1}{2}=\frac{{{V}_{S}}}{1.5}\] \[{{\operatorname{V}}_{S}}=0.75V\]
