Situational Problem ( 3 - 4) An automobile engine develops 33.5 hp at 1,000 rpm. The clutch used to transmit this power in a single plate clutch with two pairs of contact surfaces. The coefficient of friction is 0.4 and the mean diameter of the disk is to be 190 mm. The average normal stress on the clutch lining is 120 kPa. 3. Determine the axial force to engage the clutch based on uniform wear. A. 1.57 kN B. 3.14 kN C. 5.28 kN D. 7.46 kN
Q1) The V thread of a screw jack has a single start with out side diameter 40 mm and 6 mm pitch. The angle of V is 55° and the load is carried on a swivel head of mean diameter 60 mm. the coefficient of friction between the nut and screw is 0.16 and that between the swivel head and the spindle is 0.1. Calculate the load required to be applied at the end of two levers each of effective length of 500 mm to raise an axial load of 1 KN and the efficiency of the lifting.
1. A collar is fitted as a tight fit on a solid shaft. In the measurement made before assembly, the outer diameter of the ring is dga=159.97 mm, the inner diameter is dgi= 100.03 mm, and the outer diameter of the shaft is dma= 100.048 mm. After assembly; a. What is the surface pressure between the shaft and the ring? b. What is the maximum shear stress? Given: Material pair steel/steel P E=2.1x10$ N/mm?, Tmax (1-Q¿)

Information about the clamp assembly in the figure is given below. Thread diameter 12 mm, root diameter 10.16 mm, pitch 1.5 mm, screw profile angle 2α=60, friction surface of table A diameter 10 mm, friction between plate A-screw end surface coefficient 0.15 and screw-nut friction coefficient 0.15 is given. If a hand force of 200N is applied to the vise arm, if applied, a) How much force is applied to the clamped part. b) Calculate the efficiency of the vise.
1- A bush roller chain drive is used to transmit 4 kW of power from the driving shaft on a hydraulic motor runs at 1200 r.p.m to the driven shaft which runs at 350 r.p.m. The drive is required to operate continuously with drop lubrication and driven machine is such that load can be regarded as fairly constant. Design the chain drive by calculating leading dimensions, number of teeth on the sprockets taking into account that the available distance between the two shafts centers is 400mm + 4% no more no less.
