A rod l m long is acted upon by a couple as shown in the figure. The moment of couple is τ Nm. If the force at each end of the rod, then magnitude of each force is s i n 30 o = c o s 60 o = 0.5

Question

A rod l m long is acted upon by a couple as shown in the figure. The moment of couple is τ Nm. If the force at each end of the rod, then magnitude of each force is s i n 30 o = c o s 60 o = 0.5, τ l, l 2 τ, 2 τ l, 2 l τ

MARKS App · Accepted Answer

Length of rod = l Moment of couple, l τ = F l s i n θ ∴ F = τ l s i n θ - τ l s i n 30 o = τ l × 1 2 Force, F = 2 τ l
