If every male on earth got a boner at the same time, the earth& #39;s rotation would slow down. Assume there are about 3.8 billion males, with an average dick height of about 80 cm off the ground.The average dick weighs about 100 grams. That& #39;s a combined mass of 380,000,000 kg of cock
Now we must make an approximation. For simplicity& #39;s sake, let us assume the penises are all evenly lined up in a ring around the equator. The equation for moment of inertia of a ring is I = massradius2. The radius of earth is about 6.371 million meters.
Therefore the radius of the approximated dick ring is 6,371,000 + 0.80 = 6,371,000.8 meters. I = 380,000,0006,371,000.82 = 1.54241022 The Earth has a moment of inertia, I = 8.04×1037 kgm2. The Earth rotates at a moderate angular velocity of 7.2921159 ×10−5 radians/second.
Using Conservation of Angular Momentum we can find the new rotation of the earth. L=Iomega= 8.04×1037 kgm2 * 7.2921159 × 10−5 = 5.862861033. 5.862861033 = (8.04×1037 + 1.5424*1022) omega -> solve for omega = 7.292115899502489e-05
This is 4.97511e-15 rad/s slower than earth& #39;s original rotation. This translates to 6.75210-10 seconds = 0.6752 nanoseconds longer per day. If we all have a boner at the same time, we will collectively be able to last 0.6752 nanoseconds longer in bed.
The end.
