A = 7.3 sqft (per letter, critical)
Wall material: Masonry (ASTM C90, 1,500 psi min)
Anchor type/size: 3/16" (#10) Rods with Adhesive
Ref: Liquid Nails, 125 psi shear
Min Embedment: 1.5"
Min edge dist: 3" Min Spacing: 3"
Anchor tensile capacity: Tcap = 110.4 lb (per anchor)
Check Anchors for Pullout
Total Reaction: Rt = 334 lb ... = P*A (per letter)
No. of anchors req'd: n = 3.0 anchors per letter ... = Rt/cap
Total anchors required: 3 anchors per letter
OK, critical letter size shown.
Limit to min (4) per letter at "KID'S GYM", min (3) per letter otherwise, bal.
