Constant torque 2.5 kW motor drives a riveting machine. The mass of the moving parts including the flywheel is 125 kg at a radius of gyration of 700 mm. One riveting operation absorbs 1000 J of energy and takes one second. Speed of the flywheel is 240 rpm before riveting. (a) Determine the reduction in speed after one riveting operation. (b) Modify the mass moment of inertia to the flywheel if the reduction in speed is to be limited to 35 rpm.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
