Answer only one questo 3. In Figure 3, the sleeve at A slides upward on the guide DE at a constant velocity of 5
m/s. The guide DE is inclined at 45° to the horizontal. Bar AC is pivoted to the sleeve
at A with a pin and slides through the sleeve at B. Sleeve B is pivoted to the ground.
Using the vector analytical method, determine
(a) the angular velocity and the sliding velocity of link AC, and
(b) the angular acceleration and the sliding acceleration of link AC.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
