QI: A double-threaded 30-mm power screw is 30 mm in diameter with a pitch of 6 mm. The coefficients of friction are 0.05 for the collar and 0.08 for the threads. The frictional diameter of the collar is 40 mm. if Tg=18 N.m: 1- Find the A vertical load on the screw, the torque used to lower the load and screw efficiency. 2- Compute all the stresses on the screw body that will cause by the load.
d) A leather round belt transmit power from small pulley rotates 1200 rpm. The diameter of small pulley is one third of the diameter big pulley. The center distance between the pulleys is twice the diameter of big pulley. The stresses in the belt should not exceed 2 MPa and belt density is 950 kg/m?. Due to the friction of rotation, the ratio tension on the tight side to the slack side is 2:1 and coefficient of friction is 0.35. For design requirement, the ratio of diameter leather round belt to diameter of small pulley is 1:18. Determine, i) Contact angle. i) Diameter belt. iii) Belt tension. iv) Torque.

E AA 2.2 Description An aluminium manifold (shown in Figure 1), is used to convey low pressure air from a supply source to an electronic device. The manifold is manufactured from a square block of aluminium, which is machined using a CNC milling machine. During the manufacturing process of the manifold, two machining setups are required (need to be machined from two sides), resulting in additional set up and machining time required for the manufacturing of the manifold. 96,00 78,00 18,00 20,00 07.00 1.60 Ø18,00 Ø14,00 10,00 SECTION A-A Figure 1: Draft views of the aluminium ma II 00'06 INN 00'S 00'96
