Tangential and Normal Components of Accleration:

Fluid runs through a drainage pipe with a 10-cm radius and a length of 10 m (1000 cm). The velocity of the fluid gradually decreases from the center of the pipe toward the edges as a result of friction with the walls of the pipe. For the data shown, v (x) is the velocity of the fluid (in cm/sec) and X represents the distance (in cm) from the center of the pipe toward the edge. 1 5 8 9 2 3 4 6 7 v (x) 195.9 195.2 194.2 192.7 190.8 188.4 185.6 182.3 178.6 174.5 Part: 0/ 4 Part 1 of 4 (a) The pipe is 10 m long (1000 cm). Determine how long it will take fluid to run the length of the pipe through the center of the pipe. Round to 1 decimal place. It will take fluid approximately 5.104 sec to run the length of the pipe through the center of the pipe. Part: 1/4 Part 2 of 4 (b) Determine how long it will take fluid at a point 9 cm from the center of the pipe to run the length of the pipe. Round to 1 decimal place. It will take fluid approximately sec to run the length of the pipe at a point 9…

A joint between two concrete slabs A and B is filled with a flexible epoxy that bonds securely to the concrete (see figure). B A B The height of the joint is h = 4.5 in., its length is L = 47 in., and its thickness is t = 0.9 in. Under the action of shear forces V, the slabs displace vertically through the distance d = 0.005 in. relative to each other. (a) What is the average shear strain yver in the epoxy? (Enter the magnitude in rad.) rad (b) What is the magnitude of the forces V (in kips) if the shear modulus of elasticity G for the epoxy is 140 ksi? kips
