backboard Force of the wind, Fw 0.35 m 2.00 m Weight of post arrangement 15° 0.25 m Weight of base A portable basketball set has a base and a post arrangement. The post arrangement consists of a post, backboard, hoop and net. The base can be filled with water to increase stability. The maximum weight of the base is about 810 N and the weight of the post arrangement is 26.0 N. The basketball set may topple over when the wind blows due to the large area of the backboard. a) Determine the minimum force of the wind, F, that will cause the basketball set to be blown over when it is at the angle shown. Ignore the effect of the wind on the base. b) The base is filled with sand instead of water. The density of the sand is greater than the density of the water. Justify what would happen to the value of Fw calculated in part (a). 2.

Drill pipes of 1000 meter original length which is between top drive drilling motor and bottom hole assembly (HWDP, collar and drill bit) is lowered into the well. The specification of drill pipe is as follows: OD=200 mm, ID=175 mm, E = 50 GPa, G=77.2 GPa weight : drill pipe = 100,000 N , bottom hole assembly = 35,000 N Before the bottom hole assembly touch the rock formation: а) Calculate the reaction force between drill pipe and top drive drilling motor b) Calculate the elongation of drill pipe After the bottom hole assembly rest/touch on the rock formation, the elongation of the drill pipe reduces by half. c) Calculate the reaction force between drill pipe and top drive drilling motor. d) Knowing that the top steel drill pipe rotates through two complete revolutions before the drill bit starts to operate, determine the maximum shearing stress caused in the pipe by torsion.

Problem 3: (Final Answer: Louckling = 17.73 ft} In protest, a flag-pole sitter climbed to the top of 2-1/2" diameter, aluminum (E = 10,000 ksi) flag pole with a moment of inertia (1) of 0.53 in'. If the flag pole is 22 ft tall, and the flag-pole sitter is 289 Ib, how high can the sitter climb before the flag pole buckles?

Question 4 Squared & ground end A multi disc clutch, as illustrated below, is used to connect a four-cylinder internal combustion engine to a roll mill. The lining material is made of cast iron (Permissible pressure 1.725 MN/m) and friction coefficient of 0.06 running in oil. If the outer diameter of the plates is limited to 200mm and the inner diameter to 100mm, compare the maximum amount of power that can be transferred at 2500 rpm by using the a) principle of uniform pressure and b) uniform rate of wear.
