2.3 A force of 600 N is applied to the end of a spanner. The perpendicular
distance between the nut and the working line of the force is 30 cm.
Calculate the following:
2.3.1
The torque on the spanner
2.3.2
The work done when the nut is turned through an angle of 60°
(2 x 2)

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
