The position of the spindle de of a lift truck is
partiallycontrolled by two inentical
linkage-and-hydraulic-cylinf\dersys tems, only onw of which is
shown. a 3000 lb spool ofelectric cable is held by the spindle in
the position shown. knowing that the load supported by the one
system shown is 1500 lb, determine (a) the force exerted by the
hydraulic cylinder on pointg, (b) the components of the force
exerted on member bcf at pointc.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
