A nervous physicist worries that the two metal shelves of his wood frame bookcase might obtain a high voltage if charged by static electricity, perhaps produced by friction. The permittivity of free space ϵ0=8.85×10−12 F/mϵ0=8.85×10−12F/m. What is the capacitance CC of the empty shelves if they have an area of 0.375 m20.375m2 and are 0.195 m0.195mapart? C=_____ FC=_____F What is the voltage VV between the two shelves if opposite charges of magnitude 2.25×10−9 C2.25×10−9C are placed on them? V=_____ VV=_____V Calculate the energy EE stored by having this charge on the two shelves.

The thin rectangular plate is uniformly deformed such that $ \varepsilon_{x}=240 \mu \varepsilon, \varepsilon_{Y}=-720 \mu \varepsilon $, and $ \gamma_{x y}=980 \mu \mathrm{rad} $. If $ a=30 \mathrm{~mm} $, determine (a) the normal $ \operatorname{strain} \varepsilon_{n} $ in the plate. (b) the normal strain $ \varepsilon_{\mathrm{t}} $ in the plate. (c) the shear strain $ \gamma_{n t} $ in the plate. Answers: (a) $ \varepsilon_{n}= $ $ \mu \varepsilon $ (b) $ \varepsilon_{t}= $ i $ \square $ i $ \mu \varepsilon $ (c) $ Y_{n t}= $ $ \square $ $ \mu \mathrm{rad} $

Consider the pipe assembly in (Figure 1). $\vec{F}_1 = \{30\hat{i} + 25\hat{j} - 30\hat{k}\} \text{ N}$ $\vec{F}_2 = \{60\hat{i} - 10\hat{j} - 25\hat{k}\} \text{ N}$ Determine the moment about point O of force $\vec{F}_1$ acting on the pipe assembly. Enter the components of the moment separated by commas. Express your answer in newton-meters to three significant figures. $M_{1O} = 0, 4, -24$ Determine the moment about point O of force $\vec{F}_2$ acting on the pipe assembly. Enter the components of the moment separated by commas. Express your answer in newton-meters to three significant figures. $M_{2O} = -22, 0, 38, 0, 680$

1 (20 points) An electric heater is embedded in a cylinder that measures 100 mm long and 5 mm in diameter. The cylinder is vertically inserted into a hole drilled normal to the surface of a large block of material that has a thermal conductivity of 5 $\frac{W}{m \cdot K}$ and a surface temperature of 25 $^\circ$C. Estimate the cylinder surface temperature ($^\circ$C) if the cylinder dissipates 50 W of heat through the block.
