I keep getting this one wrong. For T1, I did 370/cos(30) = 427.24 lb tension , and -427.24 x cos(30)= -370. I also tried T1=820, and T2=-710.14, which was not correct as well. Thank you for your help on these two parts
Please no plagiarsm and copy the answer from the chegg thanks A rectangular wooden beam (fb = 5.9 MPa, E = 17.3 GPa) has a cross-sectionalarea of 250 mmby 500 mm. The length of the beam is 15 meters with pin and roller supports every fifth points. A vibratingmachine weighing 500 kg is located at the mid-lengthof the beam. The machine produces anunbalanced force of 500 N operating at 300 rpm.Determine the following: a) maximum static deformation under the weight of the machine,b) maximum dynamic stress in the beam section under the unbalanced force,c) force transmitted to the support, andd) adequacy of the beam against bending. Use a dampingratio of 5%.

An assembly of rods is composed of a rectangular rod and a square square tube according to the figure below. The unit is loaded with the torque M. The yield strength is 310 MPa, the modulus of elasticity 210 GPa and the transverse contraction number 0.31 in both the square tube and in the rectangular bar. Dimension the unit, i.e. determine dimension a so that a flow safety of at least 1.5 is achieved. Also calculate the total distortion if L is set to 10 · a. The torque M is 10 Nm. If you want, you can check the result via Inventor's calculation module. Dimensions a start and end from the middle of the square beam goods (center to center).
