The finished dimensions of the conduit are 66.6 inches back-to-back (B2B) with the first stub length (Stub 1) of 21.9 inches and the second stub length (Stub 2) of 14.2 inches. The gain for your bender is 3.32 inches. (Round your FINAL answer to the nearest tenth or one decimal place.) - Answers OAL = (Stub 1 - Bender Gain) + B2B + (Stub 2 - Bender Gain) = (21.9 - 3.32) + 66.6 + (14.2 - 3.32) = 96.06 ≈ 96.1 inches The ? must always be the primary source of force used to bend conduit. pedal e y - Answers A It can be assumed that the take-up value is the same for all benders of the same size. Select one: True False - Answers False In order to place the bending mark in the correct position on the conduit, the take-up must first be subtracted from the ? . -to-back distance it length length - Answers D Determine the proper distance (D) of a pencil mark from the end of a piece of 1-inch EMT when the desired stub-up (Stub 1) length of a 90° bend is 33 inches. - Answers Distance (D) = Stub - Bender Take Up = 33 - 8 = 25 inches Determine the proper distance (D) of a pencil mark from the end of a piece of ¾-inch EMT when the desired stub-up (Stub 1) length of a 90° bend is 30 inches. - Answers Distance (D) = Stub - Bender Take Up = 30 - 6 = 24 inches Benders are manufactured to create a specific ? . angle type t s - Answers D Determine the proper distance (D) of a pencil mark from the end of a piece of ½-inch EMT when the desired stub-up (Stub 1) length of a 90° bend is 23 inches. - Answers Distance (D) = Stub - Bender Take Up = 23 - 5 = 18 inches Determine the overall length (OAL) of a 1-inch EMT conduit with a total of two 90° bends. The finished dimensions of the conduit are 61.4 inches back-to-back (B2B) with the first stub length (Stub 1) of 13.0 inches and the second stub length (Stub 2) of 21.5 inches. The gain for your bender is 4.02 inches. (Round your FINAL answer to the nearest tenth or one decimal place.) - Answers OAL = (Stub 1 - Bender Gain) + B2B + (Stub 2 - Bender Gain) = (13.0 - 4.02) + 61.4 + (21.5 - 4.02) = 87.86 ≈ 87.9 inches Determine the overall length (OAL) of a 1-inch EMT conduit with a total of two 90° bends. The finished dimensions of the conduit are 51.9 inches back-to-back (B2B) with the first stub length (Stub 1) of 14.8 inches and the second stub length (Stub 2) of 12.4 inches. The gain for your bender is 3.89 inches. (Round your FINAL answer to the nearest tenth or one decimal place.) - Answers OAL = (Stub 1 - Bender Gain) + B2B + (Stub 2 - Bender Gain) = (14.8 - 3.89) + 51.9 + (12.4 - 3.89) = 71.32 ≈ 71.3 inches The ? mark indicates the position of the conduit where the bend will begin to be formed. - Answers B All hand benders include a hook, ? , handle, and foot pedal. e - Answers D
