Using the method of sections, determine the absolute value of the force in member DB of the loaded truss $($see Figure $1).$ The truss has a height $"$b$"$ of $9\mathrm{.}5$ m and the length of member AB and DC is $"$a$"$ of $8\mathrm{.}0$ m$.$ The truss is loaded with a force $"$T$"$ of $2\mathrm{.}00$ kN at joint C$.$ The truss has a pin connection at joint A and a roller connection at joint B$.$

Use $3$ significant figures in your answer.
