. Air entrainment is a process of entrapping tiny air bubbles in concrete mix in order to increase the durability of the hardened concrete in freeze-thaw climates. After 35 days, the breaking stress [in psi] was measured for concrete samples with and without air entrainment. Based on the data, does the air entrainment process increase the breaking stress of the concrete

For a bronze alloy, the stress at which plastic deformation begins is 274 MPa and the modulus of elasticity is 118 GPa. (a) What is the maximum load that may be applied to a specimen having a cross-sectional area of 316 mm2 without plastic deformation? (b) If the original specimen length is 132 mm, what is the maximum length to which it may be stretched without causing plastic deformation?

Task 1Water is retained in a 1 m wide rectangular section channel by a sluice gate that canpivot about its base, as shown below. Determine the total force on the gate due to thewater, the position where it is considered to act and the tension in the horizontalretaining cable attached to the top of the gate when the depth of water in the channelis 1.5 m. The density of water is 1000 kg/m3.Cable tension = T2 m1.5 mPivot
