2. Determine the axial force in each leg of the tripod shown. 3. A horizontal circular platform of radius \( R \) is supported at three points \( A \), \( \mathrm{B} \), and \( \mathrm{C} \) on its circumference. A and \( \mathrm{B} \) are \( 90^{\circ} \) apart, and \( \mathrm{C} \) is \( 120^{\circ} \) from A. The platform carries a vertical load of \( 400 \mathrm{~N} \) at its center and another load of \( 100 \mathrm{~N} \) at a point \( D \) on the circumference diametrically opposite \( A \). a. Determine the vertical reactions at all three supports. b. If the platform is not fastened at support \( A \), what is the maximum load that can act at \( D \) before tipping occurs?
