QUESTION 2 Consider a two-degrees-of-freedom system shown below. k₁ woo kz oooo kz oooo m2 F2 What is the amplitude of vibration of mass 1 oscillating at the input frequency? (This is just another way of asking for the amplitude of the particular solution). The answer must be positive. Use scientific notation with 3 significant figures. Omit units. Use m1 = 1 kg m2 = 1 kg k1 = 127 N/m k2 = 106 N/m k3 = 169 N/m F1 230 cos(1.7t) N F2 = 0.

Please solve the following

Consider the Wheatstone bridge shown in the image. Suppose: R3 ˆ= R4 ˆ 200 ΩR2 =ˆ variable calibrated resistorR1 ˆ= transducer resistance ˆ 40x ‡+ 100 When x ˆ=0, what is the value of R2 required to balance the bridge? If the bridge is operated in a balanced condition in order to measure x, determine the relationship between R2 and x.

A certain stress sensor is mounted on an aircraft wing that is subject to periodic wing gusts. The stress can be approximated by a sinusoidal function (i.e. sine wave) with an average 2,381 kPa and amplitude 112 at a frequency of 6 Hz. Determine the maximum stress value in kPa. (Provide the answer using 2 decimal places).

E IVP Consider a 3-element axial vibration model of a fixed-fixed bar. Use finite element analysis to determine the first two natural frequencies w1= a where and b are scalars, I is the length of the bar, E is Young's modulus and p is the density. Determine the value of b using 3 decimal places. and w2= b E = IV P

can you gudie me simple how we get this proof ??????

For a short period of time, a m = 3400 kg truck has a frictional driving force of FD= (650- +²) N acting on the wheels, where t is in seconds. At t = 0, the truck has a speed of of v₁.
