A 3 m thick clay layer (cu 5 60 kN/m2 and g 5 19.0 kN/m3 ) is underlain by a weaker clay (cu 5 30 kN/m2 and g 5 18.0 kN/m3 ) to a large depth. A 2.0 m wide square foundation is placed at 1.5 m depth below the ground level. Determine the maximum column load that can be allowed on the foundation with FS=3

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
