2 m k = 500 N/m 2 m Prob. 11-41

The unstretched length of spring AB is 3 m. If the block is held in the equilibrium position shown, determine the mass of the block at D.

Problem I A 2.25-kg slender rod AB and a 1.85-kg slender rod BC are connected by a pin at B and by the cord AC. The assembly designed by engineers can rotate in a vertical plane under the combined effect of gravity and a couple M applied to rod BC. Knowing that in the position shown, the 300 mm angular velocity of the assembly is zero and the tension in cord AC is equal to 25.0 N, determine; A (a) the angular acceleration of the assembly (b) the magnitude of the couple, M 400 mm C 400 mm AM B

Use Conjugate-Beam Method. Consider 250 mm x 250 mm section and E = 200 GPa. a=4.5 b=26 c=10 Determine: Vertical Reaction at C in kN. Moment Reaction at C in kN-m.

The plane rectangular gate can pivot about the support at B. For the conditions given, is it stable or unstable? Neglect the weight of the gate. Justify your answer.

NOTE: PLEASE INCLUDE AT LEAST 3 DECIMAL PLACES
