collar B has a mass of 4 kg and is attached to a apring of constant k = 1500 N/m and of undeformed length 0.4 m. The system is set in motion with r = 0.2 m, v theta = 6 m/s, and v r = 0. Neglecting the mass of the rod and the effect of friction, determine the radial and transverse components of the velocity of the collar when r = 0.5 m.
Calculate the force required to punch out a rectangular hole 100m x 50mm in a 2mm thick aluminium sheet. The ultimate strength in shear is 125 MN/m^2.
What are the design implications for the location and positioning of solar cells? Explain why the use of solar cells might be more appropriate in some regions of the country.
