A uniform rod is 4m long and weights 10kg . If it is supported on a kinetic edge at one meter from the end, what weight placed at that end keeps the rod horizontal.

A uniform rod of length 1 m mass 4 kg is supports on two knife-edges placed 10 cm from each end. A 60 N weight is suspended at 30 cm from one end. The reactions at the knife edges is.

A metal bar 70 cm long and 4.00 kg in mass is supported on two knife edges placed 10 cm from each end. A 6.00 kg weight is suspended at 30 cm from one end. Find the reactions at the knife edges. Assume the bar to be of uniform cross-section and homogeneous.

A metal bar 70 cm long and 4.00 kg in mass is supported on two knife edges placed 10 cm from each end. A 6.00 kg weight is suspended at 30 cm from one end. Find the reactions at the knife edges. Assume the bar to be of uniform cross-section and homogeneous.

A uniform rod AB, 4m long and weighing 12 kg, is supported at end A, with a 6 kg lead weight at B. The rod floats as shown in figure with one-half of its length submerged. The buoyant force on the lead mass is negligible as it is of negligible volume. Find the tension in the cord and the total volume of the rod
