    Designing a Gear Train: Power Transmission and Input Power Calculation

    Thanks for the replies, here is the question in full: A gear train is to be designed to transmit power from shaft 1 to shaft 2 with the following condition: (i) Shaft 1 (driven by an electric motor) rotates at 100 revs min–1. (ii) Shaft 2 is to rotate at 400 revs min–1 in the opposite...

    Designing a Gear Train: Power Transmission and Input Power Calculation

    Homework Statement A gear train is to be designed to transmit power from shaft 1 to shaft 2 with the following condition: Shaft 1 (driven by an electric motor) rotates at 100 revs min–1. Shaft 2 is to rotate at 400 revs min–1 in the opposite direction to shaft 1 against a load of 200 Nm...

    Calculating Poisson's Ratio with a Modulus of Rigidity & Young's Modulus

    Hi, I'm wondering if someone can point me in the right direction with this question. A material has a modulus of rigidity of 100 GNm-2 and a Young's Modulus of 250 GNm-2. Calculate the expected value of Poisson's Ratio for the material. Poisson's Ratio is expressed as transverse strain / axial...
