17.3.30
A homogeneous equilateral triangular plate with a mass m = 5 kg rotates in the vertical plane under the action of a pair of forces with a moment M, with a constant angular velocity ω = 10 rad / s. Determine the modulus of the hinge reaction in the position of the plate, when this reaction is greatest. The size l = 0,3 m. (Answer 136)
