The safety factor used for WACO standard post shores is____________.

The rolling shear constant of a plyform Class 1 BB 1/2″ is _______________. DO NOT WRITE THE UNITS.

Calculate the external lateral distributed load (LL) to be used for the bracing design of a wall formwork that is 17′ high. DO NOT INCLUDE THE UNITS IN YOUR ANSWER.

Calculate the lateral concrete pressure for a wallformwork. The wall is 15′ high, 30′ long and 1′ thick. Concrete will be placed in 2 hours. Cement is type 1 with retarders and is normal weight (150 pcf). Temperature is 80°F, Slump is 6″ and vibration depth is 3′. Calculate minimum and maximum required concrete pressure.

Calculate the external lateral distributed load (LL) in plf to be used for the bracing design of a wall formwork that is 16′ high.  DO NOT INCLUDE THE UNITS IN YOUR ANSWER.

What is the  weight coefficient  (Cw) of a concrete that weighs 165 pcf? Include calculations if needed.

The allowable working load of a WACO standard post shore 7’0” long is ___________. DO NOT INCLUDE THE UNITS IN YOUR ANSWER.    

Exercise 1- The final design for a wall formwork is as follow: Concrete lateral pressure=720 psf Wall height is 12′ Wall length is 40′ Wall thickness is 12″ Materials: 2×4  No 2 Douglas Fir-Larch 7/8 in. B-B Plyform Class I Snap Ties 2800 lbs Wedges are 1.5″x4″ Final design: Stud spacing = 12 in Wale spacing = 24 in (design uses double wales) Tie spacing = 20 in Bracing spacing = 10 ft

Actual stress in wall bracing is compared to the following material property____________.

This is the same fact pattern as that above – Question 1 part b Mathis Family Dentistry Corporation is owned as follows: Josh – 200 shares Josh’s son, Jack – 200 shares Dale – 300 shares Wind River Family Dentistry Corporation – 300 shares Jack owns 40% of Wind River Family Dentistry Corporation. Dale is unrelated. Mathis Family Dentistry redeems all of Josh’s shares for $55 per share on 12/31. Josh’s AB in his Mathis Family Dentistry stock was $6,000 ($30 per share) prior to the stock redemption. Assume Mathis Family Dentistry has total E&P of $150,000.   B. Are there any other options available to Josh if he fails to qualify for sale/exchange treatment under the bright line tests? Justify your answer.
