- (Civil eng.) The maximum load that can be placed at the end of a symmetrical wooden beam, such as the rectangular beam shown in Figure 2.20, can be calculated as the following: L=S1dc L is the maximum weight in lbs of the load placed on the beam. S is the stress in lbs/in2. I is the beam’s rectangular moment of inertia in units of in4. d is the distance in inches that the load is placed from the fixed end of the beam (the “moment arm”). c is one-half the height in inches of the symmetrical beam. For a 2” × 4” wooden beam, the rectangular moment of inertia is given by this formula: I=baseheight3=12=24312=10.674 c=(4in)=2in a. Using this information, design, write, compile, and run a C++ program that computes the maximum load in lbs that can be placed at the end of an 8-foot 24 wooden beam so that the stress on the fixed end is 3000lb/in2. b. Use the program developed in Exercise 9a to determine the maximum load in lbs that can be placed at the end of a 3” × 6” wooden beam so that the stress on the fixed end is 3000lb/in2.arrow_forwardSimplify the following expressions according to the commutative law: a.

- As an OCTAVE pogram: A 1 kg mass is rests on a frictionless 1 meter long ramp and compresses a k = 4000 N/m spring a distance of 5 cm. The ramps angle of incline varies from 10 to 50 degrees, in increments of 10 degrees. For each angle of incline, determine if the block will slide off the top end of the ramp after it is released from the Spring. Output each angle of incline and whether of not the block reaches the top of the ramp.arrow_forwardThe two blocks of Figure 6.17 are attached to each other by a massless string that is wrapped around a frictionless pulley. When the bottom 4.00-kg block is pulled to the left by the constant force P, the top 2.00-kg block slides across it to the right. Find the magnitude of the force necessary to move the blocks at constant speed. Assume that the coefficient of kinetic friction between all surfaces is 0.400.arrow_forwardCalculate the value of g and h in the following equation.arrow_forward
