Question

The value of mass m for which the 100 kg block remains in static equilibrium is

• A. $35kg$
• B. $36kg$
• C. $83kg$
• D. $85kg$

Answer 1

The correct option is B $36kg$

From the diagram, for mass

$T=mg$,

for $100kg$ mass,

$T+100Mg\cos {37}^{\circ }=100g\sin {37}^{\circ }$

$mg+100\times 0.3\times 10\times \frac{4}{5}=100\times 10\times \frac{3}{5}$

$m+24=60$

$m=36kg$
