A turnbuckle is used to connect two rods, one having right handed and other, having left handed V-threads. The angle of V-threads is 60 degrees. The rods have a mean diameter of 2 cm and 3 threads per cm. The coefficient of friction between the rods and the nut connecting the rods is 0.15. Find the torque required on the nut to produce a pull of 4 kN. Assume that rods do not twist.

MoodleVUT belt engages the smaller pulley horizontally. It is understood that the tension in the slack side of the belt remains the same at both ends of the inserted jockey pulley. Diameters are respectively m=700 mm for the driven pulley and a 330 for the driver with a coefficient of friction of and 0.28 between the belt and each pulley. Pulleys are mounted on parallel axes kept 1.257m apart. Angle 0 70° between the radius (tangential to the belt) and the horizontal is not to be confused with contact angles. Analyse the belt drive system and calculate: The contact angles of the open belt drive (without the jockey pulley) are respectively 0d %3D rad on the driver side and 0m rad on the machine/driven side. %3D The take-up pulley keeps the top/lack side of the belt horizontal on top of the driver pulley, resulting in a modified contact angle of rad at the driver pulley. As a result of the reaction of of magnitde 100N due to the take-up pulley, the tensile force in the slack side of the…
