Ahorizontal aluminum rod 4.8 cm in diameter projects 5.6 cm from a wall. a 1200 kg object is suspended from the end of the rod. the shear modulus of aluminum is 3.0 ? 1010 n/m2. neglect the rod's mass.(a) find the shear stress on the rod. (n/m2)(b) find the vertical deflection of the end of the rod. (m)

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
