3. What's the volume of hydrogen that can be produced during the reaction of 25 g of iron with excess water, at 100 °C and 150 kPa, taking into account

12-95. The basketball passed through the hoop even though it barely cleared the hands of the player B who attempted to block it. Neglecting the size of the ball,determine the magnitude va of its initial velocity and the height h of the ball when it passes over player B.

4-P4Before the trunk of a large tree is felled,cables AB and BC are attached as shown.Knowing that the tensions in cables AB and BC are 555 N and 660 N, respectively,determine the moment about 0 of the resultant force exerted on the tree by the cables at B.

8-P8. Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is transmitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components of reaction at the journal bearing C and thrust bearing D if0 = 45°. The bearings are in proper alignment and exert only force reactions on the shaft.

8-P10. The rectangular plate shown weighs 75 lb and is held in the position shown by hinges at A and B and by cable EF. If the hinge at B is removed and the hinge at A can exert couples about axes parallel to the y and z axes, determine (a) the tension in the cable, (b) the reactions at A andВ.

Consider the triangle wave shown in the Figure below as a periodic function with period 2n. Determine the Fourier series that represents this function, y(t). Plot the first three partial sums over the range from -n to +n.

4 -P8A 20-N horizontal force is applied perpendicular to the handle of the socket wrench. Determine the magnitude and the coordinate direction angles of the moment created by this force about point O.

For a certain thermistor B= 3,420 K, and the resistance at the reference tempcratureof 0 °C is known to be 4,010 Q. When used for a temperature measurement, theindicated thermistor resistance is 2,315 2. Determine the temperature (°C).3.

A pilot of an aircraft knows that the vehicle in landing configuration will glide 2.0 x 10' km from a height of 2.00 X 10(3) m. A TV transmitting tower is located in a direct line with the local runway. If the pilot glides over the tower with 3.0 x 10(2) m to spare and touches down on the runway at a point 6.5 km from the base of the tower, how high is the tower?

Find the air-fuel ratio of a 4-stroke, 1 cylinder, air cooled engine with fuel consumption time for 10 cc as 20.0 sec. and air consumption time for 0.1 m³ as 16.3 sec. The load is 16 kg at speed of 3000 rpm. Also find brake specific fuel consumption in g/kWh and thermal brake efficiency. Assume the density of air as 1.175 kg/m³ and specific gravity of fuel to be 0.7. The lower heating value of fuel is 44 MJ/kg and the dynamometer constant is 5000.

*12-16. A particle is moving along a straight line with an initial velocity of 6 m/s when it is subjected to a deceleration of a = (-1.5v/2) m/s², where v is in m/s. Determine how far it travels before it stops. How much time does this take?
