Find the gross income, the adjusted gross income, and the taxable income. Base the taxable income on the greater of a standard deduction or an itemized deduction. The taxpayers are married, filing jointly, earned wages of $57,600 and $47,300, and received $3500 in taxable income from investments. They contributed a total of $8300 to tax-deferred retirement plans. The interest on their home mortgage was $3885, they contributed $580 to charity, and they paid $2875 in state taxes. Click the icon to view the 2021 marginal tax rates and standard deductions. The gross income is $ (Simplify your answer.) The adjusted gross income is $ (Simplify your answer.)

HOMEWORK #4B: STRAIN & LOAD SENSORS (Individual Homework) - TORQUE CELL The figure below shows a torque cell designed to measure the torque T applied to a solid circular shaft of diameter D. The torque cell is made of four strain gauges mounted to form a full-bridge Wheatstone circuit. It is known that the strains and torque are related by: 16T1 + v21 = -82 = 83 = -84 TD E, where ε (i=1,2,3,4) are the strains in the four gauges, and E and v are the Young's modulus and Poisson's ratio of the shaft, respectively. Determine the instrument sensitivity S between the output voltage Eo and the applied torque T. Gage 1 Gage 3 Gages 3 and 4 on opposite side Gage 4 Gage 2 + 1 2 Eo Right 3 4 -Ei+

The PV diagram below shows the cyclic process abc involving 0.6 mol of an ideal gas. p (Pa × 10$^5$) 8.0 c 6.0 b 4.0 a 2.0 V (m$^3$) 0 0.020 0.060 | 0.040 0.080 (a) What are the temperatures of the gas at points a, b, and c? (b) How much work is done in each leg of the process? (ab, bc, and ca)? Over a full cycle, does the gas do work on the surroundings, or do the surroundings do work on the gas? (c) How much heat is added to or removed from the gas during one full cycle? Is heat added or removed? (d) Assuming that this cycle takes 0.2 seconds to complete, how much work is done (by the gas or sur- roundings) in one minute? (e) If the direction of the cycle were swapped (i.e., clockwise instead of counterclockwise), how would your answers to parts (b) and (c) change?
