4-70 what i ask

# Equilibrium ## Problem 4-70 The two beams shown in Figure P4-70 are bolted together with spacers between them at B and C. Determine which bolt is in tension and what tensile load it is carrying. ### Figure P4-70 Description: - A horizontal beam is shown, supported by bolts labeled as A, B, C, and D. - The distances between the bolts are as follows: A to B is 2 feet, B to C is 3 feet, C to D is 1 foot, and D to the end of the beam is 1 foot. - To the right of bolt D, a distributed load is acting on the beam. The distributed load starts at 30 lb/ft and increases to 120 lb/ft over a span of 5 feet. ![Figure P4-70](Figure_P4-70.jpg) [Illustration not provided] ## Problem 4-71 Determine the reactions at A, B, C, and D of the system shown in Figure P4-71. ### Figure P4-71 Description: - Another horizontal beam is depicted, supported by bolts labeled as A, B, C, and D with distances between them. - The distances between the bolts are: A to B is 3 feet, B to C is 6 feet, C to D is 8 feet, and D to the end of the beam is 2 feet. - On this beam, two triangular distributed loads are applied: - The first load, peaking at 80 lb/ft, spans from A to B. - The second load, peaking at 30 lb/ft, spans from B to D. ![Figure P4-71](Figure_P4-71.jpg) [Illustration not provided] ### Diagrams Explanation: - **Figure P4-70** illustrates a beam subjected to an increasing distributed load from 30 lb/ft to 120 lb/ft over a 5-foot span. The load increases linearly from left to right. The beam is supported at four points: A, B, C, and D, with specified distances between these points. - **Figure P4-71** shows a beam with two triangular load distributions. The first triangular load increases linearly to a peak of 80 lb/ft from A to B. The second triangular load increases linearly to a peak of 30 lb/ft
