A rectangular carbon block has dimensions 2.0 x 2.0 x 25 cm. What is the resistance between the square ends at 60 degrees C? The resistivity of carbon at 20 degrees C is 35 mW . m and the temperature coefficient of resistivity at 20 degrees C is -0.0005 per degree C.
Consider the following. (a) A rectangular block has the dimensions { x W x h. When a battery with a voltage AV is connected across the end faces as shown in the left figure above, a current 1; flows through the circuit. If the same battery is connected across the top and bottom faces of the block as shown in t right figure, what is the current 1, that flows through the circuit? Give your answer in terms of I.....
A rectangular bar of aluminum (2014-T4) has a length of 2.400 m and cross-sectional dimensions of 25 mm x 50 mm when the temperature is 20 C. a. At what temperature would the length be 2.405 m if the bar is unrestrained? b. If the temperature is increased an additional 30 C while the bar is restrained from growing lengthwise, compute the resulting stress in the bar. c. Is the stress level safe?
A sample of a rectangular solid is taken and measured. It has the following dimensions: 135.4 in x 157in x 110.9 in. If that sample has a mass of 1,125kg, what is the density of the substance, in grams/cm^3? (Note: the volume of a rectangle = l x w x h). I got 2900 g/cm^3 but my study partner got .29 g/cm^3.
Find the Moment of inertia of: a) The rectangular solid formed by 0≤x≤a,0≤y≤b, and 0≤z≤c by calculating Ix, Iy, Iz. [Hint: Compute one of the moments directly and then reason about the other cases via symmetry]. b) The x, y and z axes of a thin plate bounded by the parabola x=−y2 and the line x=−y with the density function defined as δ(x,y) = 1/y.

Find the volume of the solid region R bounded superiorly by the paraboloid z=1-(x^2)-(y^2), and inferiorly by the plane z=1-y taking into account that when equaling the values of z we obtain the intersections of the two surfaces produced in the circular cylinder given by 1-y=1-(x^2)-(y^2) => (x^2)=y-(y^2), as the volume of R is the difference between the volume under the paraboloid and the volume under the plane you can obtain the dimensions for the integrals and calculate the volume
