Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.
With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively.
The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage.
Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.

EFEKTİF GÜÇ
Motorun belirli hız ve yük konumlarında krank milinden elde edilen güce denir. Motor gücü, momentin açısal hız
ile çarpımıdır.
Ne = Me x ω
Motorumuzun tam yükte ürettiği maksimum moment 200 Nm olup bu moment motorun @2400 d/dak. hızla
dönmesi sırasında elde ediliyor. Verilen bilgilere ve eşitliklere göre;
n= 2400 (d/dak), π = 3.14, Me= 200 (Nm)
Açısal hız: ω= 2 x π x n / 60 (rad/san)
ω= 2 x π x 2400 / 60 (rad/san)
ω= 251.33 (rad/san)
Güç: Ne = Me x ω (watt)
Ne = 200 (Nm) x 251.33 (rad/san)
Ne = 50266 (watt)
Bu gücü kW cinsinden yazmak için 1000’e bölüyoruz ve ardından beygir cinsine çevirmek için 1.36 ile çarpım
yapıyoruz.
Ne = 50.266 (kW)
Ne = 50.266 x 1.36 = 68.36 (BG) elde edilir.

İvme olmadığı için; a=0, Fe=0, Ne=0
Yokuş olmadığı için; α=0 ֯, Fy=0, Ny=0
Hava direncini m/sn ve m/dak. cinsinden yazalım.
Vtaşıt= 100 km/h= 27.78 m/s = 1666.8 m/dak. (1h= 60 dakika, 1 dakika=60 saniye, 1km=1000m)
Lastiğin çevresi; Id = 2πr = 2xπx(0.35m) = 2.20 m (Dinamik Lastik Yarıçapı: 0.35 m)
Bunların sonucunda; nt= Vtaşıt / Id = (1666.8 (m/dak) / 2.20 m) = 758 d/dak (rpm)
Viteslerdeki motorun dönme hızları; nm = nt x Iv x Id
4. Viteste; nm = nt x Iv x Id = 758 (d/dak) x (1.00) x (4.00) = 3032 d/dak
5. Viteste; nm = nt x Iv x Id = 758 (d/dak) x (0.69) x (4.00) = 2092 d/dak
nm Motorun Dönme Hızı (d/dak)
nt Tekerlek Dönme Hızı (d/dak)

Bunlara ek olarak hava direncini düşündüğümüzde, ihtiyaç duyduğumuz ekstra güç;
Nh = (0.5 x Cd x A x ρh x V2 ) x V
Nh = (0.5 x 0.35 x 2.50 m2 x 1.293 kg/m3 x 27.782 m2/s2 ) x (27.78 m/s)
Nh = 12128 Watt
Bunlara ek olarak yuvarlanma direnci düşünüldüğünde, ihtiyaç duyduğumuz ekstra güç;

Sonuçta toplam gerekli olan güç ise;
Nt = Nh + Nr
Nt = 12128 watt + 6949 watt
Nt = 19077 W
NOT: Taşıttaki aktarma organlarının verimi, ηa = %90 yani ηa=0.90 ‘dır.
Gerekli olan motor gücü;
Ne = Nt / ηa
Ne = (19077 W) / (0.90)
Ne = 21197 W = 21.20 Kw
Beygir cinsinden yazmak istersek;
Ne = Ne x 1.36 = 21.20 x 1.36 = 28.8 BG

VİTESTE SEYREDEN ARACIN 100 Km MESAFEDEKİ YAKIT TÜKETİMİ
Şekil 1’de aracın motor performans eğrisi verilmiştir. Burada bir önceki alanda gerekli hesaplamalar yapılmıştır.
Bunun sonucunda ise bazı sonuçlara ulaşılmıştır. Bunlar;
3032 rpm ve 5.4 bar basınçta aracın yakıt tüketimi 280 g/kWh ‘tır.
100 km’deki hacimsel yakıt miktarı ise;
G= Ne x BSFC
G = 21.20 x 280 = 5936 g/saat
Hacimsel olarak 5936 / ρb = 5936 / 0.76 kg/l = 7.8 litre/100 km (ρb = Benzinin Yoğunluğu, 0.76 kg/l)
nm (4. Viteste Motorun Dönme Hızı) 3032 d/dak

Aracın yüklü toplam ağırlığı = 1900 kg ve 475 kg/her teker için;
Her bir tekere 475 kg düşüyor bu yüzden endeks 82 olur. Hız Sembolü ise V olarak kabul edilmiştir. Yani
maksimum hızı 240 km/h olarak belirlenmiştir.
