Alright Mukisa — let's do this. Step 1: Determine the tension in the strings supporting the 4kg mass. The 4kg mass is in equilibrium. The weight of the mass acts downwards, and the vertical components of the tension in the two strings act upwards. Each string makes an angle of 60^ with the upward vertical. Let T be the tension in each string. The weight of the 4kg mass is W = m g = 4g. For vertical equilibrium: 2T (60^) = 4g Since (60^) = (1)/(2): 2T ((1)/(2)) = 4g T = 4g Step 2: Find the angle for the 8kg mass. The 8kg mass is in equilibrium on a smooth inclined plane. The tension T pulls the mass up the plane, and the component of gravity pulls it down the plane. The component of gravity acting down the incline is m_1 g () = 8g (). For equilibrium along the incline: T = 8g () Substitute the value of T from Step 1: 4g = 8g () Divide both sides by 8g: () = (4g)/(8g) = (1)/(2) = ((1)/(2)) = 30^ Step 3: Find the angle for the 6kg mass. The 6kg mass is in equilibrium on a smooth inclined plane. The tension T pulls the mass up the plane, and the component of gravity pulls it down the plane. The component of gravity acting down the incline is m_2 g () = 6g (). For equilibrium along the incline: T = 6g () Substitute the value of T from Step 1: 4g = 6g () Divide both sides by 6g: () = (4g)/(6g) = (2)/(3) = ((2)/(3)) Using a calculator: ≈ 41.81^ The angles are: = 30^, ≈ 41.8^ Send me the next one 📸
