A thin rod 5 mm diameter is held between two chucks 0.8 m apart and deflects 0.5mm under its static weight. The rod weighs 1.508 N/m and the flexural stiffness is 6.136 N m². Calculate the lowest critical speed in rpm taking into account the distributed mass
There are two pairs of closed soft tooth surface spur gears A and B,Parameters of A: modulus m = 2mm, number of teeth Z1 = 40, Z2 = 90 , width of teeth b = 60mm.Parameters of B : modulus m = 4mm, number of teeth Z1 = 20, Z2 = 45 , width of teeth b = 60mm.The accuracy of the two pairs of gears is grade8, and other conditions are the same. Try to compare the contact fatigue strength and bending fatigue strength of the two pairs of gears? And explain the reason.
A 2hp motor is to drive a food shredder. The motor is projected to run at 1450 rpm and the required speed at the food shredder is 60 rpm. Design a double reduction drive consisting of belt and chain for this application. Please give solution and show drawing if needed
A mini motorcycle is driven by a combustion engine with mechanical transmission. The 12Hp motor spins at a speed of 1150 rpm. The motorcycle runs at a linear speed of 45 km/h on 12-inch wheels. Preliminary center to center distance is 13”. This type of motorcycle requires two strands (conical double sleeve assembly) and is subjected to hard shocks. Can I get a detailed explanation for Choice of chain and sprocket. (Standard part number, see catalog) https://pdf.directindustry.com/pdf/martin-sprocket-gear/general-catalog/9091-246439.html
A multi plate friction clutch is used to transmit the power from the engine to a rotor which has a mass of 152 kg and a radius of gyration of 0.34 m. The inner and outer radius of the clutch disc is 0.055 m and 0.217 m respectively. The clutch plate has 4 contact surfaces (n = 4) and the axial thrust is 379 N. The flywheel of the engine rotates constantly at 1,106 rpm. Calculate the time required to accelerate the rotor from rest if the clutch is suddenly engaged. Take μ = 0.42. Assume uniform wear in clutch.
A 2:1 speed reduction drive (Fig Q4) between two parallel shafts at 1200 mm centre distance is being provided by a V-belt of mass 0.5 kg/m. The diameter of the driving pulley is 200 mm and the driving shaft rotates at 900 rev/min. The driven pulley is 400 mm diameter. The angle of the pulley grooves is 40°, and the coefficient of friction between belt and pulleys is 0.35. If the maximum beit tension is 400 N determine: (i) The linear belt speed and the centripetal tension due to that belt speed. (ii) The angle of lap on each pulley (iii) The maximum power that may be transmitted Ø200 1200 Ø400

Explain the Schematic Diagram in this problem. (tanginamo1 is the problem) and (tanginamo2 is the schematic diagram) Provide a reasonable explanation, thank you!
Note: If you don't know the solution please leave it but don't give me wrong solution. A flat open belt drive is used to transmit a power of 25kW from a motor shaft rotating at 950 rpm. The radius of the pulley of the motor shaft is 125mm while the radius of the puller of the driven shaft is 450mm. The center distance between the shafts is 2,250mm. the coefficient of friction is 0.25 and the density of the belt material is 950 kg/m^3. The belt width is 126 mm. The allowable stress is 2.6MPa. Determine the thickness of the belt.
A cross belt system gives a speed reduction of 6:1 and the centre distance between the pulleys is 2.5 m. The effective radius of the driving pulley is r, = 80 mm and it runs at the speed of 550 rpm. The grove angle of pulleys is 25°. The belt has a mass of 0.35 kg/m and the coefficient of friction of 0.3. If the tension in the belt is not to exceed 650 N, calculate the power that can be transmitted by drive.
