1. A cylinder with a mass 0,20 kg is sliding downwards through a vertically positioned pipe. A thin oil layer exists between the cylinder and the pipe's internal surface. Centerline of the cylinder and the pipe overlap. (Yon =8044.2 N /m? ; vol=6-10° m²/s). Find the change in the speed of cylinder in the pipe with respect to its unit displacement and the shear stress that acts upon the oil layer. A A L= 150 mm 73.8 mm 74 mm 0.1 mm

1. A cylinder with a mass 0,20 kg is sliding downwards through a vertically positioned pipe. A thin
oil layer exists between the cylinder and the pipe's internal surface. Centerline of the cylinder and
the pipe overlap. (you =8044.2 N /m³ ; voli=6-10° m/s). Find the change in the speed of cylinder in
the pipe with respect to its unit displacement and the shear stress that acts upon the oil layer.
