145992 A block of mass \(90 \mathrm{~kg}\) is suspended by three strings \(A, B\) and \(C\) as shown in figure. Tensions in the strings \(A, B\) and \(C\) respectively are \(\left(\mathrm{g}=10 \mathrm{~m} . \mathrm{s}^{-2} \sin 37^{\circ}=0.6, \cos 37^{\circ}=0.8\right)\)

145993 A box of mass \(m\) is in equilibrium under the application of three forces as shown below. If the magnitude of \(F_{1}\) is \(10 \mathrm{~N}\), what is the magnitude of \(F_{3}\) ?

145994 A block of mass \(3 \mathrm{~kg}\) is pressed against a vertical wall by applying a force \(F\) at an angle \({30^{\circ}}^{0}\) to the horizontal as shown in the figure. As a result, the block is prevented from falling down. If the coefficient of static friction between the block and wall is \(\sqrt{3}\), then the value of \(F\) is (use, \(g=10 \mathrm{~m} / \mathrm{s}^{2}\) )

145995 A block is between two surfaces as shown in the figure. Find the normal reaction at both surfaces. [Assume \(g=10 \mathrm{~m} / \mathrm{s}^{2}\) ]
