The truss system below is supported by a pin at A and a roller at C. When unloaded, truss member AC has length L = 2022 mm. The truss members are made of steel pipes with cross-sectional area Ac = 3265 mm? and elasticity modulus E = 216 GPa. A vertical and a horizontal load of magnitude P= 521 kN are applied at joint B. The angle is 0 =44º

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
