The 6-inch by 6-inch timber has a unit weight of 38 #/fn and is held in a horizontal position by the concrete anchor. The length, L is 16 feet. Calculate the minimum weight that the concrete anchor must be in order to hold the timber in the horizontal position under water as shown in the figure below. Assume that concrete y 150 #/n³. Hinge timber Concrete anchor a. 84 pounds b.110 pounds O. 146 pounds Od.279 pounds Oe. Problem cannot be solved, not enough information is given

A unreinforced concrete beam is 6in wide and 12 in deep and has a point load P at the third points of the span. How large can the point load P be before the beam cracks if the f't = 400 psi? P 8ft 50 lbs 100 lbs 400 lbs 600 lbs * 8ft P 8ft

A 500-N concrete block is to be lifted by the pair of tongs shown. 500 N 45 mm 90 mm 45 mm 90 mm 75 mm D 105 mm E 360 mm 315 mm 500 N G Determine the normal force (this is horizontal) in N perpendicular to the friction force on each tong in contact with the block.

Given that the Gerber beam is drawn. Calculate and draw SFD,BMD,NFD Note : 1 ton = 1000kg Solve max in 25-30 mintes thank u
