Solution of the D8 Option 08 Dievskaya VA Malyshev IA
Sold <10Product description
Schemes 1-30 show the mechanical system consisting of a design and striking it on the body. The design can be rotated about an axis passing through the fixed point O. It consists of homogeneous thin rods 1 and 2, or the homogeneous plate 3 and 4. Point cargo weight rods of 1 m length is 25 kg, the weight of 1 m2 of a plate - 50 kg weight point load - 20 kg. Dimensions of parts of the structure are shown in meters.
The body 5 (material point) T5 = mass of 30 kg, moving with a velocity v = 4 m / s, hits the fixed structure at the point A, the punch is completely inelastic.
Determine the angular velocity of the structure after the impact and her perceived impact impulse. Find also lost at impact kinetic energy of the system.
