In deformed reinforcing bars, adhesion and lateral friction are insignificant sources of bond strength.

There are several types of stretching that can be used to aid in flexibility. In particular, dynamic stretching is which of the following?

A simply supported beam with dimensions of b = 18 in., h = 30 in., d = 27.5 in., and L = 22 ft supports a uniform service (unfactored) dead load of 2.2625 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.2 kips/ft. The beam is reinforced with five No. 8 Grade 60 bars. The concrete strength is 9,700 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 166.2 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 209.5 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 6.8434 in.

A high-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. Suppose that the radius r increases at the rate of 0.02 inches per second and that r = 36 inches at time t = 0. Determine the equation that models the volume V of the balloon at time t, and find the volume when t = 360 seconds. (5 points)

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 9 No. 5 bars at a depth of 24 in. The top row contains 7 No. 5 bars at a depth of 18.5 in. Determine the effective (centroidal) depth, d, of the steel.

Reinforced concrete structures normally do not crack when carrying service loads.

The ________ of the snowboard needs to be waxed, and the _________ of the snowboard needs to be sharpened.

Frostbite is a mild form of frostnip in which the skin is not yet frozen.

If the following is a polynomial function, then state its degree and leading coefficient. If it is not, then state this fact. f(x) = -15×5 – 7×4 + 3 (5 points)

In the guided mindfulness meditation on the present moment, there are goals to focus to reduce anxiety of the future and regrets of past and to help us to reduce unnecessary thought processes. All of the following statements apply to this meditative process except which one?
