Answer» Mass of the wooden block = m= 6 kg dimensions = 30 cm × 15 cm × 10 cm the weight of the wooden block applies a thrust on the table top. That is,Thrust = F = mg= 6 kg × 9.8 m/s²= 58.8 N Area of a side = length × breadth = 15 cm × 10 cm = 150 cm² = 0.15 m² Pressure = thrust/ areaPressure = 58.8 /0.15= 392 N/m² The same thrust in implied when it lies on the given dimension.Area= length × breadth= 30 × 15= 450= 0.45 m² Pressure = 58.8/0.45= 130.66 N/m² |
